DevVGA.h@ 78218

Last change on this file since 78218 was 77965, checked in by vboxsync, 6 years ago
Devices/Graphics: more preparations for drawing the pointer cursor in-device. bugref:9376: Complete hardware cursor implementation in VMSVGA. This change 1) moves the host cursor moved callback and the host cursor capability change callback out of the VBVA part of the graphics device and into the generic part, where they will presumably be implemented. It 2) also stops reporting the host cursor position to the guest via VBVA (this was always treated as optional by the Additions, and a position of (0, 0) treated as no host support) and always reports that the host can handle hardware cursor drawing, which is the case with all current front-ends and will be more so when we can do drawing in the device.
