Denis Gomes f0623ff89c M7: show a magnified image's pixels on the canvas ...

Zoomed in on an image, the canvas smoothed it with bicubic sampling, so
a screenshot under inspection went soft at every edge and its pixels
could not be told apart. Checking a screenshot of a live page against
its design up close needs the pixels as they are.

The canvas now samples an image paint at the nearest pixel once each
image pixel covers two or more device pixels. Below that the image stays
smooth: between 1x and 2x nearest sampling draws pixels one and two
device pixels wide side by side, which looks jagged rather than sharp.

Exports, thumbnails, PDF and SVG are unchanged: the switch is a render
option, magnified_image_pixels, that only the canvas sets, and the
retained renderer reuses a render only when it matches. Pixel preview
was not a fit: it rasterises the whole canvas at 1x or 2x, so vectors
and text go blocky along with the image.
