1. func_set for setting render func.. :)
2. fixes for size set for setting native buffer resolution/size - changing obj
size by a resize is not the way to go.
3. changes in policies were not enacted always. now they are.
4. a DEFAULT 64x64 buffer size :) so you have something at least as opposed to
0x0 :)
5. some other things...
also added my simple test case (i patched mine into elementary_test thus why
its created in a callback)
