This patch is the result of several discussions on our irc channels.
I amended the commit message to:
st/nine: Always use user constant buffers
We had several reports of users hitting bugs
with the other path to upload constants,
and switching to the user constant buffer
path solves the bugs.
User constant buffers are expected to be slower
for Nvidia cards, so ideally this patch should be
reverted when the path is fixed.
I add this patch to the list of patches I will merge today.
