A good start, still needs a bit of tweaking though, but at least the
major problem is solved.  Enlightenment and expedite no longer bitch.

expedite -e gl -a

#####Test Result#####
evas fps speed: 30.31
evas fps speed(weighted): 27.18
testcase count: 95
date: 2014-07-28 12:47:55
evas version: 1.10.99.0
profile: n800
window size: 720, 420
loop count: 128
engine: gl
full screen: 0

es2gears still has the same problems though.

Finally, progress!  B-)
