From: Keith Whitwell Date: Fri, 4 Apr 2008 12:18:09 +0000 (+0100) Subject: draw: move code to run pipeline from pt to new file X-Git-Tag: 062012170305~17580^2~390^2~1978 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=0b20d1b9b5e0514a68ab460d748753d29df2e70b;p=profile%2Fivi%2Fmesa.git draw: move code to run pipeline from pt to new file Add facility for draw_vbuf.c to reset these vertex ids on flushes.
