Additionally +.B libgamma +have support for Windows Graphics Device Interface (Windows GDI) +under Windows and Quartz using CoreGraphics under OS X. However +Windows GDI and Quartz/CoreGraphics do not receive first-party +testing on their target platforms but do receive first-party +testing using a compatibility layer that translates the calls to +RandR calls.
