Resize

[mrzaxaryan]

Hi what an awesome project!
Maybe you can add resizing support?
I added gl.viewport(0, 0, gl.canvas.width, gl.canvas.height); into start2d function.
Is it good idea?

Hi, thanks!

I cant add changing the gl.viewport because sometimes you want to draw just to a tiny part of the viewport, but feel free to call gl.viewport before calling start2D.
