... when clipping, if they have an alpha channel
Right now, this case is only reachable through PDB, but it will become
relevant for the flip tool soon.
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.
...instead of transforming it
Add gimp_matrix3_will_explode() which determines if a transform
matrix will blow up something in a rectangle to infinity, and use
the function so set both the GIMP and GEGL code paths to clip the
transform to the input size.
and pass them where we know the buffer could be from another image.
Pass "NULL, 0" if we know it's the same image.
Add gimp_layer_new_convert_profile() which takes the newly created
layer and the ICC data/length; call it from both
gimp_layer_new_from_gegl_buffer() and gimp_layer_new_from_pixbuf().
gimp_layer_new_convert_profile() is empty, this is just
infrastructure.
And along with it a lot of stuff like the drawable preview cache, the
gegl tile manager backend, temporary gimp_gegl_buffer_foo() stuff, and
the remaining bits of performance.
The projection is in an evil semi-ported state which makes it work
ok-ish for stuff like layer moving, but absolutely unbearable for
painting, there is also an off-by-one rendering glitch at some zoom
levels.
It made the transform code hard to read and never belonged into the
tile manager anyway. It's a simple pixel buffer that should not know
about any position in an image. Instead, pass around the offsets of
tile managers explicitly, so everything is less obscure for the price
of having more parameters. This will also help replacing TileManagers
with GeglBuffers.
This was actually documented to be the return value of all transform
procedures since 1.2, but it was always broken and returned the
passed-in drawable. Therefore it's only fixed for the new item API,
the old procedures keep their semantics (and will all be deprecated
anyway).
Instead, add utility functions that calculate the centers for rotate
and flip and use them where we used to pass "auto_center". This looks
pretty much poinless, but a commit will follow that makes it look
better...
There is nothing drawable-specific in there, and having them on
GimpItem enables some simplifications, esp. in upcoming PDB
wrappers. None of these refactorings is in this commit though.
Description of undo actions should be marked as action descriptions,
and not as commands. This is required for translation for some
language (like Hebrew) that require a different grammatical tense for
describing actions
(gimp_drawable_transform_affine)
(gimp_drawable_transform_flip)
(gimp_drawable_transform_rotate): also transform the layer mask if we
are transforming a layer and there is no selection (which causes the
entire layer to be transformed).
