Merge pull request #20 from foxblock/master

Mandelbot Has an Intern
The option of perspective correct texture mapping is implemented (spSetPerspectiveTextureMapping(1)), but not optimized, so it should be very slow in pandora and co.

testsparrow is better now
I did a lot of things. First of all I removed SP_PRIM_ACCURACY. I totally forgot, why I implemented is once and it doesn't seem to make sense, it just makes the whole lib more complex...
Furthermore I optimizased the perspective texture mapping. Now it could be used in a real szenario! :D
I optimized again. I don't think, that it changes much, it was just... because I can.
Clean up + changes in tests because of new sparrow version
testmesh removed, but forgot to change the Makefile, too...
The faster deactivation of dirty hacks should be the default value.
if no zoom and no rotation is passed, spRotoZoomSurface can directly call the spBlitSurface function
Add getter in sparrowFont for some special purpose
Bug in sparrowFile
Changes... Changes everywhere!

new mini feature
spFontWidth was buggy
Fancy new feature - you can add every utf8 letter in a textBundle with one function call. :)
Changes for gp2x
For some reason the projection with fast_division is still buggy...
I fixed stuff.
