Daniel Eklöf	73b4d5d05a	font: add support for fallback fonts ... A top-level font now has a list of fallback fonts. When a glyph cannot be found, we try each fallback font in turn, until we either find one that has the glyph, or until we've exhausted the list. To make this actually work in practise (read: to make performance acceptable), the cache is re-worked and is now populated on demand. It also supports non-ASCII characters, by using the 4-byte unicode character as index instead. Since having an array that can be indexed by a 4-byte value isn't really viable, we now have a simple hash table instead of an array.	2019-07-30 18:04:28 +02:00

Daniel Eklöf	9e57ba2108	font: add font_glyph_for_utf8() ... This function fills in a struct glyph with glyph bitmap data for the provided utf-8 character (essentially a FT_Bitmap wrapped in a cairo surface).	2019-07-28 20:37:59 +02:00

Daniel Eklöf	9ccc8433c3	initial grid implementation ... This allows us to render *something*, even though it's inefficient, stupid and far far away from the real thing.	2019-06-13 16:24:35 +02:00
