mesa/st: Signal state changes when depth_clamp is emulated
v1 implemented by Erik Faye-Lund <[email protected]> v2: - Add GS and TES - fix constants state update flags (Erik) v3: don't update rasterizer when depth_clamp is lowered (Erik) v4: Correct NewDepthClamp and also set flags for NewClipControl (Erik) v5: Also set shader_has_one_variant property acording to possible depth_clamp lowering (Marek) Signed-off-by: Gert Wollny <[email protected]> Reviewed-by: Reviewed-by: Marek Olšák <[email protected]>
