		WARNING :: Droid Sans font with autohinter becomes bad, without autohinter looks great, but becomes smallish, cant help
		even the smallish is so good, that i am using it on desktop
		
		but cannot be used as a substitution for arial, since 12px (which is very common on websites) becomes small as if tahoma 10px
		
		Noto sans does better in this case, can be used as arial substitution without loss of size
		noto sans is slightly fatter than droid sans
		
		Open sans is much fat, and open sans bold looks bad, hence we choose noto sans as the replacement for arial
		
		
		Download the following fonts
		Droid fonts whole sets
		
		
		Download from google web fonts
		open sans all styles
		noto sans all styles
		noto serif all styles

		================================
		LCD optimized 96 dpi
		"Sharp'N'Clear" font settings
		with emphasis on 'msttcorefonts'

		tested on Ubuntu GNU/Linux 5.10
		================================
		by Obi Bok
		Gmail: obibok
		http://linuxtuneup.blogspot.com
		================================
		Why was this conceived?

		- some font families look better hinted by Byte Code Interpreter (BCI)
		while other fonts look better hinted by Auto-Hinter
		- hinting type affects italic and bold fonts differently
		- antialiasing needs to be adjusted according to font families and sizes
		
		Essentially, there is no one single rule that works for all fonts.

		NOTE:
		- Verdana @ 8pt doesn't render '2' and '6' right
		- Arial shows 'Z' distorted in Firefox 1.5

		"The relationship of pixels to points depends on the number of pixels
		per inch, which is typically some 'standard' value corresponding to
		default screen fonts. For example, MS Windows has two standard sets of
		screen fonts initially designed for IBM display systems: 'small' (VGA)
		and 'large' (8514/A). 'Small' fonts are 96 pixels per inch, 'large' are
		120. Macintosh systems render type at a nominal 72 pixels per inch, i.e.
		one pixel = one point. Some display systems using scalable screen fonts
		allow fine tuning of pixels per inch to suit user preferences."

		FIXME: Verdana renders characters '2' and '6' slightly distorted
				so it will be substituted with Arial.
				
		EDIT Silver Moon : not replacing verdana with arial.
		hey verdana is slightly fatty, how about replacing it with open sans or noto sans
		open sans is fattier compared to droid sans
		
		BAH, it looks good
		
		Open Sans is cramped at 11px with autohint = true 
		'sa' the s and a will stick badly
		'50' the 5 and 0 will stick badly
		
		But 12px onwards Open Sans is better than Noto Sans
		
		But the vote goes to noto sans for verdana replaced to maintain beauty at 11px
		
		Another note
		noto sans has single stroke small g , open sans has the 2 round style g
		noto sans p is thin, open sans p is better looking

Great stuff, thanks! I forked it to get rid of the many warnings "Having multiple values in isn't supported and may not work as expected" you get with the latest versions of fontconfig, due to this commit.

As I was not sure if the original code was having the intended effect, I used the recommended way to disambiguate the multiple values: split them in multiple <match> elements.

See also this relevant Ubuntu bug report.

Is this warning about multiple values critical and indeed "does not work as expected"? I don't like the idea to multiply the config entries just to get rid of warnings..

Does anyone know if this still applies in 2020, assuming one runs an up-to-date distro like Ubuntu -- surely not?

People need to start demo-ing their screenshots, LMAO.
