From 6705188cc5234de633839e73dfcfc9016d29f32a Mon Sep 17 00:00:00 2001 From: Mathias Fröhlich Date: Thu, 1 Nov 2018 19:03:26 +0100 Subject: mesa/st: Factor out array and buffer setup from st_atom_array.c. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Factor out vertex array setup routines from the array state atom. The factored functions will be used in feedback rendering in the next change.
