David Turner finally admitted:
I previously thought that implementing sub-pixel hinting and positioning
would be the next step required to improve text rendering with FreeType,
but obviously simply using the LSB/RSB deltas to adjust inter-character
space has much more obvious benefits.

My question again. Why is it better to pass lsb/rsb knowledge to higher
level than to teach freetype to render a single word and provide an
interface for that?
There are several reasons not to do that in FreeType:
- the font engine doesn't do caching, so performance is going to suck

Hi Behdad,
Hi David,
I'm not sure if I understand what these lsb/rsb stuff is. Is there
anything here that cairo/pango should be doing that it's not already?
I'll try to summarize the issue as succintly as I can.
