hw/xwin: Improve data returned for RANDR queriescygwin-patches-for-1.19
Set a linear gamma ramp. This avoids the xrandr command always warning
'Failed to get size of gamma for output default'
(perhaps we should be using GDI GetDeviceGammaRamp(), if possible?)
Make CRTC report non-zero physical dimensions initially
