This initial version of the driver only supports glClear{,Color,Depth}()
for now.
Since the only publicly available documentation for the VideoCore 3D
architecture (the VideoCore IV 3D Architecture Reference Guide) just
covers an older revision of the VideoCore 3D architecture, I used
Mesa's v3d_packet.xml as a reference to get definitions for the control
records of the VideoCore VII.
To determine which control records need to be generated for a minimal
example, I used Mesa's `V3D_DEBUG` environment variable and set it to
`cl` to make it dump the control lists it generates for a basic OpenGL
test program.
