2020-11-18	Fix image uploads being random data when canvas read access is blocked (#15180)	ThibG
	Fixes #15178 PR #11499 introduced a way to deal with all-white canvas, but newer Firefox versions set random data instead. This PR detects whether canvas operations are reliable by comparing the results on a hardcoded 2×2 pixels image, and memoizing the result. This should be both more reliable and faster than the previous check.
2020-04-25	Fix uninformative error message when uploading unsupported image files (#13540)	ThibG
	Attempting to upload image files that the browser is unable to load results in “Oops! An unexpected error occurred.” This commit changes the error handling so that an unprocessable image results in the file being sent anyway, which might cover a few corner cases, and provide a slightly better error message.
2020-04-18	Fix uploaded image orientation in some browsers (#13493)	ThibG
	Some browsers (at least recent Chrome versions) automatically take image metadata into account when drawing images into a canvas. There seem to be no way to prevent that behavior, and the only way to detect it seems to compare with a known image. See: https://github.com/w3c/csswg-drafts/issues/4666 Solution adapted from: https://github.com/blueimp/JavaScript-Load-Image/commit/1e4df707821a0afcc11ea0720ee403b8759f3881

2018-07-28	Resize images by area instead of fixed dimensions (#8083)	Eugen Rochko
	To improve the way super tall or super ride images are treated, the numbers remain the same, 1280x1280 and 400x400, but if an image is less in one dimension than the other, the other can become larger Thanks to @WAHa_06x36@mastodon.social for the tip
