LibGfx+LibWeb: Support per-glyph font fallbacks in canvas text painting
...
Instead of using the first font from the FontCascadeList for all glyphs
in a text, we perform a text shaping process that finds a suitable font
for each glyph and returns a list of glyph runs, where each glyph run
represents consecutive glyphs using the same font.

LibGfx+LibWeb: Don't include start.x in GlyphRun width
...

run width. This is not correct and would be revealed by the upcoming
changes.
