1 /**@file
2 This is the main routine for initializing the Graphics Console support routines.
3 Remaining Tasks
4 Add all standard Glyphs from EFI 1.02 Specification
5 Implement optimal automatic Mode creation algorithm
6 Solve palette issues for mixed graphics and text
7 When does this protocol reset the palette?
