This adds a *very* simplified version of the UNICODE BIDIRECTIONAL
ALGORITHM (https://www.unicode.org/reports/tr9/), that can render most
bidirectional text but also produces awkward results in a large amount
of edge cases, and as such, this should probably be replaced with a
fully spec compliant implementation at some point.
This commit removes the only 3rd party library (and its usages)
in serenity: puff, which is used for deflate decompression. and
replaces it with the existing original serenity implementation
in LibCompress. :^)
This adds a new structure 'Typeface' to the FontDatabase that
represents all fonts of the same family and variant.
It can contain a list of BitmapFonts with varying size but of
the same family and weight or a pointer to a single TTF font
for all sizes of this Typeface.
With this patch it is possible to create PNG files. Only minimal options
are supported. The PNG is created with one big IDAT chunk containing
only non-compressible DEFLATE blocks.
