Add batched drawing methods#142

Internally Clyde batches drawing, however when drawing hundreds / thousands of the same quad the batch checks add up. This just omits those checks and directly draws instead. Same with skipping color modulation. Long-term could probably figure out a way to SIMD the transforms better.

I think color and the transform multiplication are the 2 biggest pertformance sinks now.

Box2Rotated PR also changes this a bit and does actually use the SIMD path but it will remind me.
