[Mesa-dev] [PATCH 09/13] mesa: reduce the size of gl_viewport_attrib

[Marek Olšák]

From: Marek Olšák <marek.olsak at amd.com>

All drivers convert these to float, so there is no reason to use double.
The piglit test that expects double precision from glGet will be adjusted
not to require it (there is a piglit patch).

gl_context::ViewportArray: 512 -> 384 bytes
