26b9fa20c1 internal/graphics: Bug fix: Race condition at QuadVertices 
QuadVertices or verticesBackend.slice reused its backend slice.
This caused a race condition. QuadVertices can be accessed from
multiple goroutines, and resetting the head and copying the data
at internal/graphicscommand might not be synced.

This change fixes this issue by basically reverting
9cb631e30f.

Closes #1546

cb73230301 graphics: Revive the special allocating method for vertices for Wasm 
It looks like the allocation cost is pretty high even on Wasm.
Revive the special method not only on GopherJS but also on Wasm.

examples/sprites kept 30FPS without this fix, but keeps 35FPS with
this fix, on Hajime's MacBook Pro 2020 (macOS Catalina 10.15.6).

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.
