- 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 is a basic implementation of an OpenEXR loader. This
"infrastructure" is required for any further work. It consists of:
* The build system changes.
* A C wrapper around the OpenEXR library, which is necessary as it's not
possible to intermix GIMP's code with C++ code.
* A basic image loader. Chroma is not supported currently, and some
other weird files like multi-view files are unsupported. These can be
added when necessary. There is no UI, but it should be straightforward
to add new features like this on top of this work.
