Fix the places that passed the color by either temp_buf_data_clear()
or memset(), and assign x and y manually, they are going to vanish
completely soon.
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.

* 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.

wanted to keep the commit separate).

(gimp_brush_clipboard_buffer_changed): for an opaque buffer,
initialize the brush mask with 255 instead of 0. Fixes bug

It makes more sense to have GimpData::dirty indicate a name change
than to invalidate the previews whenever the name changes.
* app/core/gimpdata.c: call gimp_object_name_changed() from
gimp_data_real_dirty() instead of implementing
GimpObject::name-changed and calling gimp_data_dirty() from there.
* app/core/gimpbrushclipboard.c
* app/core/gimppalette.c
* app/core/gimppatternclipboard.c: call gimp_data_dirty() in place
of gimp_object_name_changed().
* app/core/gimpbrushgenerated.c (gimp_brush_generated_dirty):
chain up unconditionally.

* app/core/gimpbrushclipboard.c
(gimp_brush_clipboard_buffer_changed)
* app/core/gimppatternclipboard.c
(gimp_pattern_clipboard_buffer_changed): limit the size of
clipboard brushes and patterns to 512x512 pixels to prevent OOM
conditions when copying from huge drawables.

* app/core/gimpbrushclipboard.c
(gimp_brush_clipboard_buffer_changed)

gimp_data_dirty() because the emission of "name-changed" takes
care of that.

* app/paint-funcs/paint-funcs-generic.h
* app/paint-funcs/paint-funcs.[ch]: implement copy_color() and
copy_color_pixels() which copy only the color bytes into a dest
that has one byte less than src. Renamed component_pixels() to
copy_component_pixels().
* app/core/Makefile.am
* app/core/core-types.h
* app/core/gimpbrushclipboard.[ch]: new GimpBrush subclass that
auto-updates its contents from gimp->global_buffer.
* app/core/gimp.c (gimp_real_initialize): add a clipboard brush to
the brush factory. Fixes bug #111082.
