X-Git-Tag: upstream/17.1.0~659
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=31970ab9a6526177c585cb92693178b7d5408916;p=platform%2Fupstream%2Fmesa.git

nvc0: Add support for NV_fill_rectangle for the GM200+

This enables support for the GL_NV_fill_rectangle extension on the
GM200+ for Desktop OpenGL.

Signed-off-by: Lyude <lyude@redhat.com>

Changes since v1:
