/**
* Performs a mapping of the buffer object like the normal GTT
* mapping, but avoids waiting for the GPU to be done reading from or
* rendering to the buffer.
*
* This is used in the implementation of GL_ARB_map_buffer_range: The
* user asks to create a buffer, then does a mapping, fills some
* space, runs a drawing command, then asks to map it again without
* synchronizing because it guarantees that it won't write over the
* data that the GPU is busy using (or, more specifically, that if it
* does write over the data, it acknowledges that rendering is
* undefined).
