Subject: Use quads instead of lines to ensure this is testing stencil functionality
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=72aeea4eea1454efcdd78908343bbebd99ebcc01;p=mesa.git

Use quads instead of lines to ensure this is testing stencil functionality
rather than rasterization.  A crutch to hw with wonky line
rasterizers.
