[Mesa-dev] [PATCH] svga: fix default case in svga_get_sample_position()

[Brian Paul]

If called for an unsupported number of samples, always return (.5, .5).
Fixes the Piglit arb_texture_multisample-fb-completeness test for
unsupported sample counts, such as 2.

Ideally, this function should not get called for unsupported sample
counts, but that'll be additional work...
