nvfx: refactor sampling code, add support for swizzles and depth tex
This is a significant refactoring of the sampling code that: - Moves all generic functions in nvfx_fragtex.c - Adds a driver-specific sampler view structure and uses it to precompute texture setup as it should be done - Unifies a bit more of code between nv30 and nv40 - Adds support for sampler view swizzles - Support for specifying as sampler view format different from the resource one (only trivially) - Support for sampler view specification of first and last level - Support for depth textures on nv30, both for reading depth and for compare - Support for sRGB textures - Unifies the format table between nv30 and nv40 - Expands the format table to include essentially all supportable formats except mixed sign and "autonormal" formats - Fixes the "is format supported" logic, which was quite broken, and makes it use the format table Only tested on nv30 currently.
