/*
* XXX: Never pass the SVGA3D_SURFACE_HINT_RENDERTARGET hint. Mesa cannot
* Note: Previously we never passed the
* SVGA3D_SURFACE_HINT_RENDERTARGET hint. Mesa cannot
* know beforehand whether a texture will be used as a rendertarget or not
* and it always requests PIPE_BIND_RENDER_TARGET, therefore
* passing the SVGA3D_SURFACE_HINT_RENDERTARGET here defeats its purpose.
*
* However, this was changed since other state trackers
* (XA for example) uses it accurately and certain device versions
* relies on it in certain situations to render correctly.
