DrawPrimitive now accepts the number of vertices, not the number of
primitives. This code was forgotten in the patch that changed this.
We're drawing triangles, so we are drawing num_primitives * 3 vertices.

In most cases we're fine with the vbo and glMapBuffer and never use the actual
heap memory copy. Try to stick to just the vbo copy and avoid allocating the
extra heap memory. In case it is needed(emulation or vertex conversion), fall
back to the old double buffering mode.

wined3d: Split vshader_program_add_param() in shader_arb_add_src_param() and shader_arb_add_dst_param().

WineD3D buffer FVFs will go away soon.

On Win2k SHITEMID only contains FileStructA.
This structure isn't padded like it is on WinXP and contains a
supplementary CHAR* member at its end which contains the 8.3 filename if
needed.

Skip this test as it doesn't work on Win2k.
CoCreateInstance is successful but IPersistPropertyBag_Load call fails.

Passing an absolute path to SetNameOf on Win2k display an error
message box about invalid characters in filename, forcing interaction
during test.

wined3d: Only update the swizzle and use map for streams that are actually used in device_stream_info_from_strided().

This fixes a regression introduced by d7c7c768
and exposed by ef2d7041. Unfortunately having
EXT_vertex_array_bgra support masks the problem, which is why the regression
tests didn't catch it.
