X-Git-Tag: android-x86-4.4-r1~2473
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=d2c7fe5389e40871a7e339dc0ecaa7f570f851ed;p=android-x86%2Fexternal-mesa.git

draw: set precalc_flat flag for AA lines too

Fixes flat shading for AA lines.  demos/src/trivial/line-smooth is a
test case which hits this.

Note: This is a candidate for the stable branches.
