Subject: [PATCH] svga: adjust line subpixel position for HWv8
This fixes two regressions on HWv8:
Piglit gl-1.0-ortho-pos
Piglit/glean fbo
This was caused by commit c2b92dada076a "svga: clamp device line width
to at least 1 to fix HWv8 line stippling"
This also fixes two conform tests: Vertex Order and Polygon Face
No Piglit/conform changes with HWv9 or later.
VMware bug 1905053
