There's that saying with infinite monkeys banging on typewriters. I started
with trying to adjust the base vertex and do something with vb_pos which did
not help. Of course I don't particularly grasp that part of the code. I haven't
worked with DirectX or OpenGL before. Actually, really haven't done much with C
either. There was one comment I stumbled across, "...could simply be set to
include the entire vertex buffer at the price of performance." Which gave me
the idea to increase vtx_size. Still I was surprised when it rendered
everything correctly.

While I could no doubt beat git into shape to generate a patch I wouldn't feel
comfortably submitting it as I don't understand the existing code in that
function much less the implications of the proposed change.

I see that Wine is in code freeze currently. Assuming proper patches were
submitted is this something that would make it into 2.0?
