Hi everyone,
while optimizing an application I found out that much time is spent inside 
vbo_exec_fixup_vertex because each time vbo_exec_FlushVertices is called the 
current vertex format is resetted using reset_attrfv, and so the information 
about the application usage patterns is lost.

Would not it be better to retain the current format? Quite probably in the 
same application, always the same attributes will be used.

I'm pretty new to Mesa internals, so I'm sure I'm missing some points...

Regars,
Alessandro Pignotti
