- [Win32] Bugfix: Context re-creation was not triggered by sRGB hint
- [Win32] Bugfix: Full screen windows were incorrectly sized and placed on some
systems
- [Win32] Bugfix: Gamma ramp functions acted on entire desktop instead of the
specified monitor
- [X11] Added run-time support for systems lacking the XKB extension
- [X11] Made GLX 1.3 the minimum supported version
- [X11] Replaced `XRRGetScreenResources` with `XRRGetScreenResourcesCurrent`
