We can remove one cache layer and speed up WidthIterator by doing less hash lookups.

This change seems to have broken several SVG tests on Windows. Could you please take a look?

patch

Cleared Andreas Kling's review+ from obsolete attachment 247360 [details] so that this bug does not appear in http://webkit.org/pending-commit.
Comment 23 Antti Koivisto 2015-09-14 14:04:53 PDT
Glyph mappings are per typeface while widths are per font (size included). Lets not do this as it would complicate future optimizations.
