*	fontselect: expose a fontprovider selection API	Stefano Pigozzi	2015-07-10	1	-1/+2
\| \| \| \| \| \| \| \| \|	Allow the user of libass to select the font provider from ass_set_fonts. This API change actually doesn't break client code which was passing `fc=1`; now the same value will autodetect a usable font provider. Also add an api to list available font providers as that is useful for client code to show drop down menus with a font provider to choose from.
*	fontselect: implement a coretext font provider	Stefano Pigozzi	2015-07-10	1	-0/+34
	Fontconfig is known to be very slow on OS X and Windows, this has to do with the extremely prohibitive cache times (which are getting even longer with latest versions of Fontconfig). This commits starts to address the problem by using CoreText on OS X to load the font data. The commit uses the simplest possible approach to load all of the data in memory and then use it to match. This causes a somewhat slow startup time (around ~400ms on my i7) but it is already better than waiting minutes for Fontconfig to cache the fonts data. A later commit will improve the speed of the match by using a hybrid approach that lazy loads in the libass database only the necessary fonts.
