q5-webgpu fallback: origin is double-translated

[keturn]

I think the origin is supposed to be in the center of the canvas in webgpu and webgpu-fallback, but it currently gets shifted both in _beginRender:

q5.js/src/q5-core.js

Lines 182 to 185 in 75b8271

	if ($._webgpuFallback) {
	$.colorMode('rgb', 1);
	$._beginRender = () => $.translate($.canvas.hw, $.canvas.hh);
	}

and resetMatrix:

q5.js/src/q5-2d-canvas.js

Line 158 in 75b8271

if ($._webgpuFallback) $.translate($.canvas.hw, $.canvas.hh);

so it ends up at the bottom-right of the screen when draw is called.

ah true! q5 no longer needs the translation in beginRender since resetMatrix runs at the start of each frame.
