+independent_blend_enable
+ If enabled, blend state is different for each render target, and
+ for each render target set in the respective member of the rt array.
+ If disabled, blend state is the same for all render targets, and only
+ the first member of the rt array contains valid data.
+logicop_enable
+ Enables logic ops. Cannot be enabled at the same time as blending, and
+ is always the same for all render targets.
+logicop_func
+ The logic operation to use if logic ops are enabled. One of PIPE_LOGICOP.
+dither
+ Whether dithering is enabled.
+rt
+ Contains the per rendertarget blend state.
+
+per rendertarget members
+------------------------
+
+blend_enable
+ If blending is enabled, perform a blend calculation according to blend
+ functions and source/destination factors. Otherwise, the incoming fragment
+ color gets passed unmodified (but colormask still applies).
+rgb_func
+ The blend function to use for rgb channels. One of PIPE_BLEND.
+rgb_src_factor
+ The blend source factor to use for rgb channels. One of PIPE_BLENDFACTOR.
+rgb_dst_factor
+ The blend destination factor to use for rgb channels. One of PIPE_BLENDFACTOR.
+alpha_func
+ The blend function to use for the alpha channel. One of PIPE_BLEND.
+alpha_src_factor
+ The blend source factor to use for the alpha channel. One of PIPE_BLENDFACTOR.
+alpha_dst_factor
+ The blend destination factor to use for alpha channel. One of PIPE_BLENDFACTOR.
+colormask
+ Bitmask of which channels to write. Combination of PIPE_MASK bits.

wrap_s
How to wrap the S coordinate. One of PIPE_TEX_WRAP.
wrap_t
PIPE_TEX_FILTER.
mag_img_filter
The filter to use when magnifying texels. One of PIPE_TEX_FILTER.
+compare_mode
+ If set to PIPE_TEX_COMPARE_R_TO_TEXTURE, texture output is computed

Whether the texture coordinates are normalized. If normalized, they will
