and instead simply return the paint_core owned buffers. Also, move
graph creation and source buffer fiddling out of perspective clone's
inner loop, and set an area to be processed manually, which makes it
responsive again.
GIMP was doing evil hacks lying to GEGL about it's pixels being in a linear
color space when they are not. This causes incorrect rendering, makes gaussian
blur misbehave etc.
The legacy projection modes should be implemented using the same 2.2 gamma
formats that are correct to specify for sRGB data. (for proper color
management in higher bitdepths; icc backend babl formats should be used.)
For the old image modes correct babl formats are:
R'G'B'A u8 - 8 bit RGB with 2.2 gamma (sRGB) with linear alpha component
R'G'B' u8 - 8 bit RGB with 2.2 gamma (sRGB)
Y'A u8 - 8 bit Grayscale with 2.2 gamma with linear alpha component
Y' u8 - 8 bit Grayscale with 2.2 gamma
Y u8 - 8 bit linear data, used for masks/channels
A u8 - 8 bit linear alpha
-----------------------------------------------
RGBA float - 32bit floating point linear light RGB
RaGaBaA float - 32bit floating point linear light RGB, premultiplied alpha
to be used for processing that needs to scale by the alpha,
(blurs, resampling etc)
R'G'B'A float - 32bit floating point sRGB with gamma, to be used where
the result depends on being closer to perceptual when
processing, can be used a cheaper alternative to CIE Lab
based modes.
-----------------------------------------------
The legacy layer modes should use the formats with gamma 2.2 only for loading
and rendering legacy XCF files correctly, in the brave new world compositing
should most likely be done in linear light with "RGBA float" and even better
"RaGaBaA float" like GEGL does for porter duff and other compositing modes.
The ability to chose the legacy layer modes should probably be hidden from the
user unless an old .xcf has been opened.

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().

it to above brush core functions. Use the get_dynamic_color() to
calculate the gradient color.

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.

2006-09-26 Michael Natterer <mitch@gimp.org>
* app/paint/gimppaintcore.[ch]: added GError** parameter to
GimpPaintCore::start().
* app/tools/gimppainttool.c (button_press): display the error in
the statusbar.
* app/paint/gimppaintcore-stroke.c: pass a NULL error, effectively
swallowing mssages. Will fix that later.
* app/paint/gimpbrushcore.c
* app/paint/gimpclone.c
* app/paint/gimpsourcecore.c: changed accordingly. Set the error
instead of calling g_message().
* app/paint/gimpheal.c
* app/paint/gimpperspectiveclone.c: implement start() and bail out
early on indexed drawables instead of showing a g_message() in
other functions that are called later.
* app/tools/gimptool.[ch]: added GError** to GimpTool::initialize().
* app/tools/gimptool.c (gimp_tool_initialize): display the error
in the statusbar. Keep the external API GError-free.
* app/tools/gimprectangletool.[ch]: added GError** to
gimp_rectangle_tool_initialize().
* app/tools/gimpbrightnesscontrasttool.c
* app/tools/gimpcolorbalancetool.c
* app/tools/gimpcolorizetool.c

* app/tools/gimpperspectiveclonetool.c

* app/tools/gimptransformtool.c: changed accordingly. Set the
errors in initialize() instead of using gimp_message().
* app/tools/gimpblendtool.c: implement initialize() and bail out
early on indexed images instead of showing a gimp_message() in
button_press().
2006-09-20 Michael Natterer <mitch@gimp.org>
* app/paint/gimpsourcecore.c: implement GimpPaintCore::start()
and set paint_core->use_saved_proj to TRUE when we are using
the destination drawable image's projection as source. Return
FALSE from start() if there is no src_drawable set and removed
checks for src_drawable != NULL further down in the code path.
* app/tools/gimpperspectiveclonetool.c (button_press)
* app/tools/gimpsourcetool.c (button_press): don't fiddle with
paint_core->use_saved_proj here.
* app/paint/gimpclone.c: implement GimpPaintCore::start() and
return FALSE if we are in pattern mode and there is no pattern to
clone from. Removed GimpPaintCore::paint() implementation because
all it did was popping a message if there is no pattern. Removed
check for pattern != NULL and cleaned up the file a bit.
* app/paint/gimpperspectiveclone.c (paint): removed message about
no pattern to clone from.
2006-09-13 Michael Natterer <mitch@gimp.org>
* app/paint/gimpclone.c (gimp_clone_motion): don't access the
src_pickable when cloning from a pattern. Fixes runtime warnings.
2006-09-09 Michael Natterer <mitch@gimp.org>
* app/paint/gimpclone.c (gimp_clone_line_image): changed src_pickable
parameter to src_type.
(gimp_clone_motion): allow the passed srcPR to have alpha even if
the source pickable is flat. Pass the correct GimpImageType to
gimp_clone_line_image().
2006-09-08 Michael Natterer <mitch@gimp.org>
* app/paint/gimpperspectiveclone.c (gimp_perspective_clone_motion):
must not clamp the paint area against the boundary of the
src_tiles. Various small cleanups.
* app/paint/gimpsourcecore.[ch] (GimpSourceCore::motion): removed
src_image parameter.
Added new virtual function GimpSourceCore::get_source() and moved
the source PR initialization code to its default implementation.
(GimpPerspectiveClone will override this method later).
* app/paint/gimpclone.c (gimp_clone_motion)
* app/paint/gimpheal.c (gimp_heal_motion): changed accordingly.
2006-09-07 Michael Natterer <mitch@gimp.org>
* app/paint/gimpsourcecore.[ch] (gimp_source_core_motion): pass
the src_offset_x and src_offset_y as separate parameters to
GimpSourceCore::motion().
* app/paint/gimpheal.c (gimp_heal_motion): changed accordingly.
* app/paint/gimpclone.c (gimp_clone_motion): ditto and use the new
values for pattern cloning instead of asuming stuff that relies on
knowledge of gimp_source_core_motion()'s internals.
2006-09-07 Michael Natterer <mitch@gimp.org>
* app/paint/gimpsourcecore.[ch] (gimp_source_core_motion): pass
the width and height of the sub-area of paint_area to
GimpSourceCore::motion().
* app/paint/gimpclone.c (gimp_clone_motion)
* app/paint/gimpheal.c (gimp_heal_motion): use the new parameters
instead of taking these values from srcPR->w and ->h, which was
very confusing.
2006-09-05 Michael Natterer <mitch@gimp.org>
* app/paint/gimpsourcecore.[ch] (gimp_source_core_motion): do a
lot of stuff that was duplicated in clone and heal. Added lots of
parameters to GimpSourceCore::motion() to get the stuff down to
clone and heal.
* app/paint/gimpclone.c (gimp_clone_motion): changed accordingly.
* app/paint/gimpheal.c (gimp_heal_motion): ditto. Made it work for
dest_drawable != src_pickable. Always add alpha to all buffers and
convert the source buffer to the dest drawable's color space
because the algorithm works only on buffers of same depth.
2006-09-03 Michael Natterer <mitch@gimp.org>
* app/paint/paint-enums.[ch]: renamed enum GimpCloneAlignMode to
GimpSourceAlignMode.
* app/paint/Makefile.am
* app/paint/gimpsourcecore.[ch]
* app/paint/gimpsourceoptions.[ch]: new classes which contain the
source selection functionality factored out of the clone core and
options.
* app/paint/gimpclone.[ch]
* app/paint/gimpcloneoptions.[ch]: remove that functionality here
and derive from the new classes.
* app/tools/gimpclonetool.c: changed accordingly.
2006-09-02 Michael Natterer <mitch@gimp.org>
* app/paint/gimpclone.c
* app/paint/gimpink.c: minor cosmetic cleanup merged from the
soc-2006-healing-brush branch.
2006-03-30 Sven Neumann <sven@gimp.org>
* app/paint/gimpclone.[ch]: use doubles for src coordinates. Added
properties for "src-drawable", "src-x" and "src-y".
* tools/pdbgen/pdb/paint_tools.pdb: resurrected cloning from
drawables over the PDB. This used to be broken for quite a while.
* app/pdb/paint_tools_cmds.c: regenerated.
