This was based on a patch originally by Kristian. It has been modified
pretty heavily to use the new callbacks from the previous patch.
v2:
- Add LINEAR and Yf modifiers to list (Ville)
- Combine i8xx and i965 into one list of formats (Ville)
- Allow 1010102 formats for Y/Yf tiled (Ville)
v3:
- Handle cursor formats (Ville)
- Put handling for LINEAR in the mod_support functions (Ville)
v4:
- List each modifier explicitly in supported modifiers (Ville)
- Handle the CURSOR plane (Ville)
v5:
- Split out cursor and sprite handling (Ville)
v6:
- Actually use the sprite funcs (Emil)
- Use unreachable (Emil)
v7:
- Only allow Intel modifiers and LINEAR (Ben)
v8
- Fix spite assert introduced in v6 (Daniel)
