Simulation support:

This function is simulated by a handling routine in Revision 2.0 (or later) of the graphics engine.

Description

GreDeviceCreatePalette is called by GreSelectPalette, to process an application's GpiSelectPalette request. The presentation driver is expected to perform any allocation and data structure initialization needed for a subsequent GreDeviceRealizePalette to succeed.

This function can be hooked by the presentation driver.
