Adjust out of surface verification for wide lines
Wide lines rasterization tests may draw lines out of
the allocated surfaces. Such situation causes verification
failures.
This change adjust the verification algorithm to ignore
missing pixels for out of surface rendering.
Components: Framework
Affects:
dEQP-GLES2.functional.rasterization.primitives.lines_wide
dEQP-GLES2.functional.rasterization.primitives.line_strip_wide
dEQP-GLES2.functional.rasterization.primitives.line_loop_wide
