Subject: mesa: add gl_driver_flags::NewScissor{Rect,Test}
X-Git-Tag: upstream/18.1.0~8961
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=4c037af9cc06f4e472eab371447ff56753a51ea4;p=platform%2Fupstream%2Fmesa.git

mesa: add gl_driver_flags::NewScissor{Rect,Test}

_NEW_SCISSOR mesa flag is set when a scissor test is enabled/disabled
or when a new rectangle is defined. However, it triggers too much
changes in the state tracker.

Actually, ST_NEW_RASTERIZER should only be called when a scissor
test is enabled/disabled, while ST_NEW_SCISSOR should be called
in both situations.

In other words, this will avoid to update the rasterizer every
time a new rectangle is defined using glScissor*().
