... which takes a GimpPrecision, and determines if its values are
bounded to the [0,1] range (which is currently only true for
integer precisions).

This fish is used for text layers, so if we let it to be
lazy-initialized, the first time one writes text in a text layer, it
generates a few seconds delay, which is really not great.

... (valgrind reports Invalid read)
Add gimp_babl_is_valid(), which takes a GimpImageBaseType and a
GimpPrecision, and determines whether the image-type/precision
combination is valid. Use this function to validate that loaded
XCFs use a valid type/precision combination, before trying to
create the image. Otherwise, we get a CRITICAL, and eventually a
segfault, when the combination is invalid.
Use the same function to validate the arguments of
gimp_image_new().
(cherry picked from commit a0a62656d2)
- Add new enum GimpComponentType which contains u8, u16, u32 etc.
- Change GimpPrecision to be u8-linear, u8-gamma, u16-linear etc.
- Add all the needed formats to gimp-babl.c
- Bump the XCF version to 5 and make sure version 4 with the old
GimpPrecision enum values is loaded correctly
This change blows up the precision enums in "New Image" and
Image->Precision so we can test all this stuff. It is undecided what
format will be user-visible options in 2.10.
This permits editing sRGB profile PNGs and other formats using sRGB storage,
without this editing a 16bit bpc PNG in u16 mode would cause banding in the
shadow areas on import. File that do not have an sRGB like gamma should be
promoted to a higher bit-depth on import.
