- This is the main routine for initializing the Graphics Console support routines.
-Remaining Tasks
- Add all standard Glyphs from EFI 1.02 Specification
- Implement optimal automatic Mode creation algorithm
- Solve palette issues for mixed graphics and text
- When does this protocol reset the palette?
