Hello! Maybe you've already seen this, but anyways:
1. Share freetype glyph name tables:
http://live.gnome.org/MemoryReduction_2fProgressTracker
2. Freetype2 has a bug where if you ask it to resize a 13x13 face to a
12.5x12.5 face, it decides that they're close enough already and does
nothing, even though creating faces from scratch for 13x13 and 12.5x12.5
would give you slightly different font metrics. Because Xft caches faces
internally, this means when you're working with fractional font sizes
Xft will sometimes give you varying font metrics depending on whether
it's reusing a face in the cache (and hitting the Freetype2 bug when it
tries to resize the face) or creating one from scratch. This in turn
occasionally causes line heights, and sometimes the intrinsic width of
text inputs which is computed from font maxAdvance, to be off by one pixel.

On a side note, I emailed the following bug report to address@hidden
back in February:
=>
version: 2.1.9 and current (dating back to the end of december)
font: Tahoma 8px
settings: native bytecode interpreter enabled, antialiasing disabled

Some glyphs have a few unndeeded pixels when rendered with the latest
versions of FreeType (see the links above). '3' is rendered fine in FT
2.1.4, '8' is displayed wrong in all versions. Looks like a round off
error to me.

May I know status of this bug? Thanks in advance.
