Changes:
- Added arbitrary angle rotation button and icon. (rotation was already available using the Ctrl button)
- Added bilinear filtering when rotating at 100% zoom.- Switching modes (Pick WB, Crop, etc...) behaviour changed.
- Olympus E-P1 brightness fixed. (Note: there is no calibration for it yet, so it will not look right, and appearance of images may change across versions)
- Added more error messages in case of program errors. It will also warn you if you have an ATI/AMD graphics chip and your drivers are too old. (Many drivers before Catalyst 9.2 contain bugs that cause problems with Scarab Darkroom)
