detection (and not build time GL headers)
- add a new debug channel for hardware vertex shaders
- hardware VS "compiler" fixes:
-> special case for address registers (MOV must be replaced by ARL)
-> add line numbers to trace (better to find why NVidia drivers complains)
-> one parse to determine temporary and address registers needs
(@todo: check GL limits)
-> remove duplicate traces from Generic ParseProgram
- try to fix D3DTADDRESS_BORDER, D3DTADDRESS_MIRROR,
D3DTADDRESS_MIRRORONCE using OpenGL extensions
- better set_tex_op: now use Runtime Extension support (and not
compile support)
- support of D3DTSS_MIPMAPLODBIAS (using EXT_TEXTURE_LOD_BIAS extension)
- correct support of D3DTSS_MAXANISOTROPY for D3DTSS_MAGFILTER and
D3DTSS_MINFILTER
- fixes for D3DTSS_MAGFILTER and D3DTSS_MAGFILTER
