Subject: st/mesa: apply DepthMode swizzle to stencil texturing as well
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=6f4a725073fcef6b7b5a7b9acdc99539fa3fa1f4;p=mesa.git

st/mesa: apply DepthMode swizzle to stencil texturing as well

Gallium doesn't present these as GL_RED-style. A swizzle is necessary to
present the proper data in the unused components.
