gallium: New cap PIPE_CAP_MAX_VERTEX_ELEMENT_SRC_OFFSET.
Introduce a new capability for the maximum value of pipe_vertex_element::src_offset. Initially just every driver backend returns the value previously set from _mesa_init_constants. So this shall end up in no functional change. Reviewed-by: Brian Paul <[email protected]> Reviewed-by: Roland Scheidegger <[email protected]> Signed-off-by: Mathias Fröhlich <[email protected]>
