Ensure that color buffers and textures are mapped (bmBufferMap) before

Browse source 
software rasterizer fallbacks.  This has two functions, firstly to
ensure that the Data pointers point to something and secondly to
ensure than any pending fences on those buffers are discharged before
allowing the software rasterizer to read/write the data.

This needs to be integrated with Brian's validate code.
