For example, in the flutter/gallery the cards zoom in as they scale in. The scale is more or less arbitrary betwen 2 and 3 based on the user's gesture input: 2.321, 2.4123123, 2.51001.

So we end up churning through the atlas, to render slightly different or identical bitmaps. We should probably round this value, ideally as much as we can without affecting fidelity.
