Hacks and fixes
===============

20220126:
node_modules/requirejs/bin/r,js
	Under Electron v14+ requirejs breaks with a SyntaxError on the 
	first char of r.js ('#!/...') -- a hackish way to fix this is to 
	comment it out, not yet sure why is this happening...
	STUB: patched by:
		make node_modules



20210122:
Marking changes twice on load...

The way .markChanged(..) is handled around .load(..) / .loadOrRecover(..) and 
in base.js seems a bit hackish -- would be goof to do this in one spot,
revise...

See:
- features/base.js ~@1179 -- 'load' handler... 
- features/filesystem.js ~@982 -- 'loadIndex' handler...



20201104:
Chrome v83 / Electron 9.3.3

WebKit canvas' .drawImage(..) ignores its and images .style.imageOrientation 
unless both are added to DOM.

FIX:
- features/app.js: img2canvas(..) quietly adds the elements to DOM and then cleans up

TODO:
- test in browser...
- test in newer versions of browser / electron...
- if not fixed report...



20200830: 
RequireJS + Electron v7+ mess up default .baseUrl

FIX:
- cfg/requirejs.js: added .baseUrl inferencing.

TODO:
- is this a bug or a feature and report as bug if needed



20200830: 
Chrome messing up fullscreen colors unless a <video> tag is present.

FIX:
- data/blank.mp4: added
- index.html / electron.html: added <video> tag with data/blank.mp4 as source

TODO:
- report this...
