I somehow thought that GL_ARB_robustness that had something for this, but
apparently it was just my imagination.
Anyway, if we particularly cared for robustness of user pointers, we could
query the OS for the virtual address range that contains a pointer. Windows/Mac
have nice APIs for that. Li
Yes, we are not getting the user buffer sizes, because OpenGL lacks
API to set them. The pointer is all you will ever have, just as it was
received from a gl*Pointer call.

We would crash when stride was bigger than the size of the buffer.
The correct behavior is to just fetch zero's in this case.
Unfortunatly with user_buffer's there's no way to validate the size
because currently we're just not getting it. Adjust the draw interface
to pass the size along the mapped

Unfortunatly gallium allows user_buffers in vertex_buffers and we
can't figure out the sizes of those, so we need to null check
the buffer to see if we can at all perform th
