Increase max VBO size back to 4MB.

Browse source 
Some meshes (e.g. pers_gardens_struct with gentangents enabled) have
>32K vertexes, and won't fit in a 2MB VBO. 0ef6c7555e had reduced them
from 4MB to 2MB. So just make the VBOs bigger again, and try not to
worry about the waste of memory.

Fixes #3026, #3042.
