[Glamor] [PATCH] Increase vbo size to 256K verts.

[He Junyan]

Hi Zhigang:

On my IVB, the result is


old: small_reslt
new: gresult
Slowdowns
=========
  xlib                  ocitysmap  1547.06 (1651.89 3.28%) -> 1884.77 
(2200.61 7.73%):  1.22x slowdown
▎

seems no effect and cause ocitysmap a bit slower.
