When launching a game, switch the graphics mode if necessary
(and by extension the pixel formats used for Graphics::Surfaces
and Sprites) to the one that most closely matches the pixel format
used in-game.
Additional Fixes:
- Fix to prevent cursor position from changing when exiting a menu.
- Fix to prevent updating of Magnification viewport position when
virtual keyboard is open.
- Cosmetic code fixes for improper whitespace and missing curly brackets.
- Remove RGB8 as a mode option because:
1) It was already commented out in the master 3DS backend.
2) There are currently no games that explicitly require it.
Notes:
- As these graphics modes are automatically implemented on a per-game basis, they
are meant for backend use only and are purposefully not accessible through the
Options menu.
- RGBA8 (aka RGBA8888) remains the default pixel format, being used for the launcher
menu, CLUT8, and for games which do not specify a particular format.
