Subject: [PATCH] st/mesa: handle texture_from_pixmap and other surface-based
textures correctly
There were 2 issues with it:
1) The texture format which should be used for texturing was only set
in gl_texture_image::TexFormat, which wasn't used for sampler views.
2) Textures are sometimes reallocated under some circumstances
in st_finalize_texture, which is unacceptable if the texture comes
from a window system.
The issues are resolved as follows:
1) If surface_based is true (texture_from_pixmap, etc.), store the format
in a new variable st_texture_object::surface_format.
2) Don't reallocate a surface-based texture in st_finalize_texture.
Also don't use st_ChooseTextureFormat is st_context_teximage, because
the format is dictated by the caller.
This fixes the glx-tfp piglit test.
