canvas is wiped on retina displays

[makc]

Unless I set data-caman-hidpi-disabled on my canvas, caman's hidpiadjustments (or similar named) routine resizes it, and this action clears its content - certainly not the effect we want.

Same problem here, i'm trying to find a solution for this very anoying on every apple retina products.
