74e204d952 graphics: Speed up DrawTriangles (#723) 
DrawTriangles is expensive and slow because of massive memory
allocation and garbage collection costs. This patch moves from ~47TPS
on my laptop (with ~24k triangles) to 60TPS. The first part
is just allocating the right size of vertex buffer up front; that
got to about 55TPS. The second part replaces the frequent
allocations of []float32 in Vertex() calls with writing the
desired values into a provided destination slice.

Time spent in drawing triangles for 1,000 frames:
	13.07s	baseline
	11.09s	preallocate whole buffer to avoid resizing
	6.13s	use new PutVertex function

This might need some cleanup, but I think it's good evidence that
the design change is viable.
