Add a "gboolean edge_lock" parameter to GimpChannel::feather() and a
"Selected areas continue outside the image" toggle to the "Feather
Selection" dialog, just like they exist for shrink selection and
border selection. At the end, convert the boolean to the right abyss
policy for gegl:gaussian-blur.

In gimp_drawable_get_active_mask(), when the drawable doesn't have
an alpha channel, set or clear the mask's alpha bit, according to
the state of the other bits, so that it never gets in the way of a
fully set/clear mask. The value of the alpha bit doesn't matter
when there's no alpha channel, however, having a uniform mask
allows us to skip component masking altogether.
Additionally, provide a default implementation for
GimpDrawable::get_active_mask() which returns a full mask, and
remove the equivalent implementation for GimpChannel.

When clearing a channel, do nothing if the channel is already
empty; otherwise, align the cleared rectangle to the channel
buffer's tile grid, so that all affected tiles are dropped, rather
than zeroed. Furthermore, only update the affected region of the
channel.

...palette views despite selected color being in the currently
selected pallette
As suggested by Massimo, changing the color comparison EPSILON in
gimppalette.c from 1e-10 to 1e-6 fixes this, and is really small
enough.
Also, generally clean up color comparison epsilons:
- use a #define, not hardcoded values for all uses of
gimp_rgb[a]_distance()
- call the #defines RGB_EPSILON and RGBA_EPSILON
- make them all 1e-6 or larger

... which specifies whether or not to update the drawable in
response to the buffer change.
Pass TRUE for "update" at all existing call sites, to keep the
current behavior.

Make sure a channel -> selection -> channel roundtrip never does any
gamma conversion.
In gimp_channel_duplicate(), make sure a created channel has the
right format, and the right data. Fixes selection -> channel.
When switching off quick mask, call gimp_item_to_selection() instead
if gimp_selection_load(), the latter was implementing a shortcut which
is now wrong.
Remove gimp_selection_load() which is now unused.
Unrelated: also remove gimp_selection_save(), it was an obvious
3-liner used only twice.
Revert commit 24fcabc1ca, which
allowed passing a NULL buffer to gimp_drawable_set_buffer[_full](),
leaving the drawable without a buffer in a semi-functional state --
this is too risky.
Instead, have gimp_drawable_steal_buffer() assign an empty 1x1
buffer to the stolen-from drawable, rather than leaving it without
a buffer at all.
... which clears the drawable's buffer, performing any necessary
cleanup, without setting a new buffer. While the drawable has no
buffer, it can only be used in a very limited way, in particular,
it may be destroyed, and it may be assigned a new buffer.
This is used by the next commit to implement
gimp_drawable_steal_buffer(), which transfers a buffer from one
drawable to another in a safe manner, leaving the source drawable
empty.
Have GimpChannel connect to the drawable buffer's "changed" signal,
so that we can invalidate the channel's boundary whenever the
buffer contents change. Currently, the calls to
gimp_drawable_invalidate_boundary() dispersed throughout the code
are not enough.
Moreover, invalidate both the boundary and the bounds in
gimp_channel_invalidate_boundary(), since both are necessary when
the buffer changes.
Replace the GIMP_BOUNDARY_HALF_WAY macro by two others : one for perceptual and
one for linear gamma.
Use the GIMP_BOUNDARY_HALF_WAY_LINEAR to compute channels and floating selection
boundaries.
Add a composite_space parameter to gimp_gegl_create_flatten_node()
and gimp_gegl_apply_flatten(), which controld the color space --
linear or perceptual RGB -- used for the operation (instead of
hardcoding it to linear).
When removing a layer's alpha channel, use the layer's composite
space for the flattening. When flattening an image, use the bottom
layer's composite space. Keep using linear space when creating a
channel or a mask from a drawable with alpha.
Largely based on a patch by Ell, with the enum type renamed and
various small changes. Adds another axis of configurability to the
existing layer mode madness, and is WIP too.
with proper value names. Mark most values as _BROKEN because they use
weird alpha compositing that has to die. Move GimpLayerModeEffects to
libgimpbase, deprecate it, and set it as compat enum for GimpLayerMode.
Add the GimpLayerModeEffects values as compat constants to script-fu
and pygimp.
Add a GimpFillType argument to GimpItem::resize() and fill type
widgets to the canvas and layer resize dialogs. Fill the new parts of
the drawable according to fill type in gimp_drawable_resize(). Make
sure places that need the old behavior get GIMP_FILL_TRANSPARENT
passed by hardcoding it in the GimpItem::resize() implemetations of
channel, mask, selection etc.
making its external API "complete". Remove the redundant
"new_base_type" and "new_precision" from the internal (vfunc) API (the
Babl format has the same information).
They are unreliable because every type checking cast discards them,
they are useless anyway, visual clutter, added inconsistently, and
generally suck. Wanted to do this a long time ago, it was a bad idea
in the first place.
isntead of the feather parameter, and pass it to
gimp_gegl_apply_border().
Make the necessary changes to the rest of the code to maintain the
current behavior.
Mass parameter alignment changes to gimpchannel.h. Sigh #2...
instead of the feather parameter.
The BORDER_STYLE_HARD and BORDER_STYLE_FEATHERED styles are implemented
using the "gimp:border" operation, as was done previously. The
BORDER_STYLE_SMOOTH style is implemented by performing a "gimp:grow" and
a "gimp:shrink", and subtracting the shrunk image from the grown image
using "gegl:substract".
gimp_channel_border() is modified to pass either BORDER_STYLE_HARD or
BORDER_STYLE_FEATHER, depending on its feather parameter, to maintain
the current behavior. The next commit replaces it with a style
parameter as well.
Mass parameter alignment changes to gimp-gegl-apply-operation.h. Sigh...
instead of just a boolean "convert_profile". This takes the logic to
figure the right target profile out of gimp_layer_convert_type(), it
can't possibly know everything about how to convert anyway, and having
the logic in the callers conveniently splits it up and distributes its
parts to the places they belong.
This commit should cause no behavor change and is just preparation for
fixing bug 765176.
For selections, it's different from gimp_edit_fill() because it
ignores the selection while filling, just as stroking does. Currently
unused, stay tuned...
also add "GType old_type" to GimpItem::convert() so implementations
can do things depending on the type of the original item.
In gimp_layer_convert(), if the original item is also a layer, and
color management is not off (with a FIXME because this is the wrong
check), pass convert_profile = TRUE to gimp_drawable_convert_type().
There is no color profile conversion anywhere behind this, this is
just an API change commit.
Which returns a boolean indicating if there is content at all, and the
bounds as double x, y, width, height because for most use cases that's
better than x1, y1, x2, y2. Wrap the method with two functions
gimp_item_bounds() which returns integer bounds and
gimp_item_bounds_f() which returns the original double bounds.
gimp_gegl_apply_feather(): add a "dest_rect" parameter to restrict
the feather area. Pass the selection bounds plus the feather radius.
For consistency, newly add gimp_gegl_apply_border,grow,shrink() and use
them in gimpchannel.c
