[Mesa-dev] [PATCH 4/8] mesa: Replace _ae_{, un}map_vbos with _mesa_vao_{, un}map_arrays

[Mathias.Froehlich at gmx.net]

From: Mathias Fröhlich <mathias.froehlich at web.de>

Due to the use of bitmaps, the _mesa_vao_{,un}map_arrays functions
should provide comparable runtime efficienty to the currently used
_ae_{,un}map_vbos functions. So use this functions and enable
further cleanup.
