Great stuff Józef and welcome back ;)

The patch looks very good to me. Except for the gl_info->limits.blends hack I
only have pretty generic style complaints (e.g. an unnecessary newline before
get_projection_matrix(), an opening brace on the same line as the 'if',
statements on the same line as the braceless 'if').

About the blend matrices count, the proper fix is probably to add a field to
d3d_info and populate it from the vertex caps in wined3d_adapter_init_gl_caps()
(and also update glsl_vertex_pipe_vp_get_caps() to advertise 4 blend matrices).
You'll then need to replace a few uses of gl_info->limits.blends in wined3d
with the d3d_info value. At a quick look only wined3d_cs_exec_set_transform()
and prune_invalid_states() need that treatment.

I guess a test would be nice to have too.

After you clean the patch up just send it to wine-patches. BTW thanks for
working on this, I was thinking about commenting on this bug that now all the
infrastructure to properly fix the bug is there but I don't plan to implement
this, it looks like you were faster :)
