Automatically connect to the global GimpColorConfig unless a different
one is set manually (like for previews that belong to a
GimpDisplayShell and should follow its color management settings. Add
public API for subclasses to get to the renderer's color
transform. Automatically color manage rendered pixbufs, just as we
already manage temp_bufs.
Now that more and more widgets are color managed, we need transforms
for all of them. Creating them is very expensive.
The new cache returns the same transform for a combination of (config,
src_profile, src_format, dest_format) and invalidates itself
automatically on config changes. The number of transforms goes down
from potentially hundreds to a handful, and the cost of a config
change from many seconds to virtually instant.
xdg-email would usually open an email client where you can edit all
fields, like recipients, mail title, etc. Setting it first in GIMP
is redundant.
Of course, these fields can still be set in non-interactive mode (in
which case, maybe xdg-email could be set to some non-interactive email
client as well).
By default, it will now use xdg-email to select the user's preferred
email client, which means it only works on platforms with xdg-email.
The sendmail implementation is still available if requested explicitly
with --with-sendmail.
Which takes two profiles and returns TRUE if converting between
them works correctly without a GimpColorTransform. Use it in
gimp_color_transform_new() to return a NULL transform if none
is needed. Took the code from gimp-gegl-loops.c.
which encapsulates a cmsHTRANSFORM and does all the pixel format
conversion magic. It has API to create transforms and proofing
transforms, and to convert pixels arrays and GeglBuffers.
Before, each place which has a transform had to keep around the
transform and its input and output Babl formats, and had to implement
lots of stuff itself. Now all that lives in GimpColorTransform,
removing lots of logic from many places, and pretty much removing lcms
from the public API entirely.
This removes including <lcms2.h>, LCMS_LIBS and LCMS_CFLAGS from
almost all directories and potentially allows to replace lcms by
something else.
Trick lcms into converting cairo-RGB24 pixels directly, by using
TYPE_BGRA_8 on little endian and TYPE_ARGB_8 on big endian. They have
the same byte order, and the alpha channel (ignored by lcms anyway)
takes the place of the unused byte of cairo-RGB24.
This saves two babl conversions around cmsDoTransform().
