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.

a073f48faf input: Bug fix: keypress event were not fired
This change suspends to 'preventDefault' on keydown events.

Now preventing navigation by pressing backspace is deprecated in
Chrome. For other keys, it looks like keyup's preventDefault is
enough to disable the browser default behavior.
