- Support for ConsoleControl protocol. Support for UGA Draw spliter.\r
- Support for DevNull Console Out. This console uses memory buffers\r
- to represnt the console. It allows a console to start very early and\r
- when a new console is added it is synced up with the current console\r

- (SourceX, SourceY) (SourceX + Width, SourceY + Height) directly to the\r
- video display rectangle (DestinationX, DestinationY)\r
- (DestinationX + Width, DestinationY + Height). If SourceX or SourceY is\r
- not zero then Delta must be set to the length in bytes of a row in the\r

- (SourceX, SourceY) (SourceX + Width, SourceY + Height) .\r

- BltBuffer - Buffer containing data to blit into video buffer. This\r

- BltOperation - Operation to perform on BlitBuffer and video memory\r
- SourceX - X coordinate of source for the BltBuffer.\r
