The one deviation from the spec here is to use this in the WOFF
TableDirectoryEntry's tag field. However, *not* making that a Tag made
a lot of things more complicated than they need to be.
This updates fonts so rather than rastering directly to a bitmap, you
can extract paths for glyphs. This is then used to implement a
Gfx::Path::text("some text", font) API, that if given a vector font
appends the path of the text to your Gfx::Path. This then allows
arbitrary manipulation of the text (rotation, skewing, etc), paving the
way for Word Art in Serenity.
An error is now returned if `numTables` is zero or greater than 4096.
While this isn't explicitly mentioned in the specification, subsequent
calculations will be incorrect if the value falls outside this range.
It wasn't enough to do it only for simple glyphs, we need to do it for
composite glyphs as well.
Fixes an issue where some glyph data was misaligned in the output and
thus ended up rendered incorrectly or not at all.
