This will make textures rehash 4x more often if they seem to be static.
Previously, 2048 for a 30 fps game meant 69 seconds before it would notice
a change. This is really long for fonts that get missed sometimes.
This takes that down to 17.5 seconds. Still quite a while, but something
a normal person is much more likely to wait for.
Hopefulyl won't hurt performance much normally.
