...in GimpRGB format.
Resolves#14754
GimpGrid properties are saved and loaded
in XCFs as GimpParasites. When we
converted from GimpRGB to GeglColor
for the fgcolor and bgcolor properties,
we caused those properties to be lost
when saving a 2.10 and below compatible
XCF in GIMP 3.0+.
This patch adds new
gimp_config_get_xcf_version () and
gimp_config_set_xcf_version () API to
libgimpconfig's interface. This allows us to
pass the intended XCF version to the
parasite serialization process, and save
as either GeglColor or GimpRGB compatible
formats based on that value.
