Add a transform matrix to GimpCanvasBoundary and get rid of the whole
BoundSeg transform code in boundary.c and gimpbrushcore.c, it was
impossible to get this right on that level. Also fix te extents of
GimpCanvasBoundary os it leaves no artifacts.
For generated brushes, dynamic input is applied on top of the set hardness as a factor.
For pixmaps, it influences the amount of blur applied to the stamp. Be warned, process is slow
for large pixmaps. The odd feature previously advertised as hardness is left in but disabled.
If I figure out what it should be exposed as, it might be made available again.

Bug 520078 – Rotate brushes
Applied patch from Alexia Death:
* app/core/gimpbrush.[ch]
* app/core/gimpbrushgenerated.c
* app/core/gimpbrush-transform.[ch]: affine transformations for
brushes. So far only scaling and rotation is supported. The
transformation is done using nearest-neighbour. This is a
regression and we need to add back interpolation before the next
release.
* app/paint/gimpsmudge.c
* app/paint/gimppaintoptions.[ch]
* app/paint/gimpbrushcore.[ch]: allow to control the brush
rotation angle.
* app/tools/gimppaintoptions-gui.c
* app/tools/gimpbrushtool.c: added UI for controlling the
brush rotation angle.
* app/actions/tools-actions.c
* app/actions/tools-commands.[ch]: add actions for controlling
the
brush rotation angle.

Applied patch from Alexia Death that prepares brushes for
arbitrary transforms by renaming stuff with 'scale' to
'transform'. Takes us one step closer to fixing bug #520078.
* app/core/gimpbrush.[ch]
* app/core/gimpbrushgenerated.c
* app/paint/gimpbrushcore.[ch]
* app/paint/gimpsmudge.c
* app/core/gimpbrush-transform.[ch]: New names of
* app/core/gimpbrush-scale.[ch]
* app/core/Makefile.am: Update.

* all files with a GPL header and all COPYING files:
Change licence to GPLv3 (and to LGPLv3 for libgimp).
Cleaned up some copyright headers and regenerated the parsers in
the ImageMap plugin.

2008-05-22 Michael Natterer <mitch@gimp.org>
Applied slightly modified and fixed patch from Alexia Death which
adds a "random" axis to the paint dynamics and fixes some issues
in the previous paint dynamics commits. Fixes bug #529431.
* app/core/core-types.h: add a "random" axis to GimpCoords.
* app/display/gimpdisplayshell-coords.c: set it to a random value.
* app/display/gimpdisplayshell-callbacks.c: on button_press,
use the dynamics from the last motion event to avoid blotches
at the beginning of paint strokes.
* app/paint/gimppaintoptions.[ch]: add random properties the same
way we do pressure and velocity. Add get_dynamic_size(),
get_dynamic_color() and get_dynamic_hardness() functions which
look at all dynamic parameters of the passed coords.
* app/tools/gimppaintoptions-gui.c: add gui for the random options.
* app/paint/gimpbrushcore.[ch]: remove calc_brush_scale() and use
gimp_paint_options_get_dynamic_size_instead().
Add "dynamic_hardness" parameters to paste_canvas(),
replace_canvas() and get_brush_mask().
* app/paint/gimpairbrushoptions.c
* app/paint/gimpclone.c
* app/paint/gimpconvolve.c
* app/paint/gimpdodgeburn.c
* app/paint/gimperaser.c
* app/paint/gimpheal.c
* app/paint/gimppaintbrush.c
* app/paint/gimpsmudge.c: calculate the dynamic hardness and pass
it to above brush core functions. Use the get_dynamic_color() to
calculate the gradient color.

Applied patch from Alexia Death that makes velocity dynamics
controlled scale properly recalculate the brush mask when
necessary (bug #533618).
* app/paint/gimpbrushcore.[ch] (gimp_brush_core_scale_mask): A
change in scale requires a recalculation of the cached brush mask.
svn path=/trunk/; revision=25696
2008-05-10 Michael Natterer <mitch@gimp.org>
Applied modified patch from Alexia Death which adds velocity
support to paint tools in the spirit of the pressure support we
already have. Fixes bug #529431.
* app/display/gimpdisplayshell-coords.c
(gimp_display_shell_eval_event): tweak velocity calculation to
work in screen coordinates.
* app/paint/gimppaintoptions.[ch]: add velocity options in the
same way as there are pressure options. Add utility functions
which return dynamic opatity and dynamic rate according to the the
option's settings and some GimpCoords' pressure and velocity.
* app/tools/gimppaintoptions-gui.c: add GUI for the velocity
options.
* app/paint/gimpbrushcore.h: remove PRESSURE_SCALE define, it's
now in gimppaintoptions.h.
* app/paint/gimpbrushcore.c (gimp_brush_core_interpolate):
inerpolate velocity too.
(gimp_brush_core_calc_brush_scale): take velocity into account.
(gimp_brush_core_get_brush_mask): always pressurize the mask in
the GIMP_BRUSH_PRESSURE because there always is velocity (unlike
pressure which is only there on tablets).
* app/paint/gimpairbrush.c
* app/paint/gimpclone.c
* app/paint/gimpconvolve.c
* app/paint/gimpdodgeburn.c
* app/paint/gimperaser.c
* app/paint/gimpheal.c
* app/paint/gimppaintbrush.c
* app/paint/gimpsmudge.c: get opacity and rate from the new paint
options utility functions which take both pressure and velocity
into account.
* app/paint/gimppaintbrush.c: take velocity into account when
calculating the gradient color offset.
* app/paint/gimpairbrush.c: do some additional fiddling with
velocity in the asynchronous airbrush timeout.
* app/paint/gimpairbrushoptions.c: override the velocity-size
property and have it default to FALSE.
svn path=/trunk/; revision=25604
* app/paint/gimpheal.c: heal from edge of brush mask
instead of edges of paint area.
* app/paint/gimpbrushcore.[ch]: export
gimp_brush_core_get_brush_mask() to enable use of mask.
svn path=/trunk/; revision=24324
2007-11-13 Michael Natterer <mitch@gimp.org>
Enable brush scaling for smudge (but only before, not while
painting). Fixes bug #471348.
* app/paint/gimpbrushcore.[ch] (struct GimpBrushCoreClass): rename
member "use_scale" to "handles_scaling_brush".
(gimp_brush_core_calc_brush_scale): apply pressure scale only if
both "handles_scaling_brush" and "use_pressure" are TRUE, and
apply the scaling from the options unconditionally.
(gimp_brush_core_get_paint_area): don't re-fetch core->scale if
"handles_scaling_brush" is FALSE to keep the brush from scaling
*while* painting.
(gimp_brush_core_create_bound_segs): use the brush scale from the
options unconditionally since that's always used now.
* app/paint/gimpsmudge.c (gimp_smudge_brush_coords): use
gimp_brush_scale_size() to figure the accum_buffer's size instead
of using the brush mask's size directly.
* app/tools/gimppaintoptions-gui.c (gimp_paint_options_gui): show
the brush scale controls for all brush tools.
svn path=/trunk/; revision=24140
2007-07-04 Sven Neumann <sven@gimp.org>
* app/paint/gimpbrushcore.[ch]: applied patch from Jens Persson
that adds a LUT to apply the jitter in polar coordinates (bug
#434532).
svn path=/trunk/; revision=22859
2007-04-13 Michael Natterer <mitch@gimp.org>
* app/base/base-types.h
* app/base/temp-buf.[ch]: remove redundant and inconsistently used
MaskBuf type and API.
* app/core/gimpbrush-scale.c
* app/paint/gimpbrushcore.[ch]: use TempBuf and its API instead.
This also optimizes away a useless memset() on brush scaling,
we completely fill each of the created buffers anyway.
svn path=/trunk/; revision=22249
2006-11-22 Michael Natterer <mitch@gimp.org>
* app/paint/gimpbrushcore.[ch]: applied modified patch from Adrian
Likins which adds a GRand to the GimpBrushCore struct and uses it
instead of using g_random_foo() functions. Fixes bug #377981.
2006-11-16 Michael Natterer <mitch@gimp.org>
Made all brushes scalable from the tool options. So far only
downscaling is supported since we lack an algorithm for bitmap
brush upscaling. Addresses bug #65030.
* app/paint/gimppaintoptions.[ch]: added "brush-scale" property.
* app/paint/gimpbrushcore.[ch]: separate pressure logic from brush
scaling logic and take paint_options->brush_scale into account.
Added gimp_brush_core_create_bound_segs() which returns BoundSegs
of the correctly scaled brush mask for the brush preview on the
canvas.
* app/tools/gimpbrushtool.c: use gimp_brush_core_create_bound_segs()
instead of doing this here (also removes all knowledge about lowlevel
stuff from this file). Connect to notify::brush-scale of the
paint options and invalidate the brush core's brush accordingly.
* app/tools/gimppaintoptions-gui.c: added brush scale slider.
* gimp/app/paint/gimpbrushcore.c
* gimp/app/paint/gimpbrushcore.h
* gimp/app/paint/gimpclone.c
* gimp/app/paint/gimppaintbrush.c
* gimp/app/paint/gimppaintoptions.c
* gimp/app/paint/gimppaintoptions.h
* gimp/app/tools/gimppaintoptions-gui.c: Apply patch from
Adrian Likins to add "jitter" to paint tools (bug #163049),
with small fixes for coding style and default jitter set
to 0.2 instead of 0.0.
2004-06-23 Michael Natterer <mitch@gimp.org>
* app/paint/gimpbrushcore.[ch]: added signal "set-brush" which is
G_SIGNAL_RUN_LAST so we can connect before and after the default
implementation. Moved the brush setting and outline invalidation
stuff to its default implementation. Also remember the outline's
width and height. Call gimp_brush_core_set_brush() from
gimp_brush_core_invalidate_cache() so "set-brush" is emitted
whenever a generated brush becomes dirty.
* app/tools/gimppainttool.c (gimp_paint_tool_button_press): don't
pause/resume but rather stop/start the draw_tool. Fixes straight
line preview aretefacts.
(gimp_paint_tool_oper_update): set the brush_core's brush before
starting the draw_tool.
(gimp_paint_tool_draw): never free the brush_core's cached brush
outline because the brush_core does that by itself now.
(gimp_paint_tool_set_brush)
(gimp_paint_tool_set_brush_after): new callbacks which pause and
resume the draw_tool. Fixes brush outline artefacts when modifying
the current brush e.g. by using the mouse wheel.
2004-06-14 Michael Natterer <mitch@gimp.org>
* app/paint/gimppaintcore.[ch]: added new virtual function
GimpPaintCore::post_paint() and call it after calling
GimpPaintCore::paint().
* app/paint/gimpbrushcore.[ch]: renamed brush_core->grr_brush
to brush_core->main_brush and reset brush_core->brush
to brush_core->main_brush in GimpPaintCore::post_paint().
* app/paint/gimpbrushcore.c
* app/paint/gimppaintcore-stroke.c
* app/tools/gimppainttool.c: removed all code which restores
the brush_core's old brush after painting since post_paint()
does this automatically now.
* app/paint/gimpclone.[ch]: moved static variables to the
GimpClone struct.
2004-05-26 Michael Natterer <mitch@gimp.org>
* app/paint/gimppaintcore.[ch]: removed "gdouble scale" parameter
and added "GimpPaintOptions" in GimpPaintCore::get_paint_area().
Check if virtual functions exist befoe calling them.
* app/paint/gimpbrushcore.[ch]: added "gdouble scale" to GimpBrushCore
and "gboolean use_scale" to GimpBrushCoreClass (defaults to TRUE).
Set scale from paint_options in GimpPaintCore::get_paint_area().
Removed "scale" parameter from gimp_brush_core_paste_canvas()
and _replace_canvas().
* app/paint/gimpsmudge.c (gimp_smudge_class_init): set use_scale
to FALSE.
* app/paint/gimpclone.c
* app/paint/gimpconvolve.c
* app/paint/gimpdodgeburn.c
* app/paint/gimperaser.c
* app/paint/gimppaintbrush.c: removed all scale calculations and
simply pass paint_options to GimpPaintCore::get_paint_area().
