* Accelerated sRGB <=> linear conversion using lookup table, this can speed up
loading of images in the compositor and simple renders quite a bit.
* Dithering now uses the Floyd-Steinberg algorithm. Previously it would simply
randomize each pixel slightly, adding noise, now that should be reduced.
Patch #29309 by David M.
- removed AVG2, was only used once.
- remove unused LONGCOPY define.
- removed BLI_STRUCT_OFFSET, was only used once, replce with offsetof
- formatting edits, split some macros over multiple lines.
- rename define DISABLE_SDL --> WITH_SDL (which was already used in some places)
- blenders interation preset was using orbit rather then turntable 3d view preference (different from factory defaults).
- tagged some unused rna args.
- define __BIG_ENDIAN__ or __LITTLE_ENDIAN__ with cmake & scons.
- ENDIAN_ORDER is now a define rather than a global short.
- replace checks like this with single ifdef: #if defined(__sgi) || defined (__sparc) || defined (__sparc__) || defined (__PPC__) || defined (__ppc__) || defined (__hppa__) || defined (__BIG_ENDIAN__)
- remove BKE_endian.h which isn't used
This fix also allows for partial update of the image, speeding up painting.
The different code path implemented will be used to upload high resolution images to OpenGL when onion branch is merged.
Due to conversion of float textures to/from sRGB, corrections made to brush color sampling to take account of the image profile. This is not 100% correct yet as texture images used for projection painting strokes are not converted to/from sRGB yet(This has been decided due to loss of precision for 8-bit formats). It will have to do for now, though.
last-minute update, exr image loading is broken, will fix asap
Not really a "bug", but it was on my todo anyways. Based on patch
[#26508] by Campbell, with a few modifications including extending
this to the Action/DopeSheet editor too.
