Nicholas Bishop 87ddcab933 Bugfix: avoid reading from an OpenGL buffer mapped write-only.
When set to solid-shading, GPU_update_grid_buffers was calling
normal_quad_v3 to output into a mapped buffer, but normal_quad_v3
reads as well as writes.

This fix actually makes a huge performance difference with my drivers
(Gallium/Radeon).
