No HDR / EDR: the framebuffer offers 8 bits per channel only #7

NSScreen.maximumPotentialExtendedDynamicRangeColorComponentValue is 1.0 and the screen depth is 24 bits per pixel. NVRMFB publishes only IO32BitDirectPixels (8 bpc), so there is no HDR or EDR on the internal panel (upstream #30). This is recorded for the feature matrix, not as a defect of the fork.
