[PATCH 2/4] d3d9/tests: Test that Direct3D9 doesn't modify the pixel format of the window it targets. (try 4)

[Henri Verbeet]

After thinking about it for a bit, I think the issue is essentially
that context_acquire() depends on context_enter() to set
context->restore_ctx when context_set_gl_context() needs to be called.
If only the pixel format is different context_set_gl_context() will
not be called.
