@ -9,5 +9,18 @@ not exactly bugs, but should be considered though:
the quality of AA text, but Monochrome and LCD hinting still suck. We
need to do something about that.
* Add CIDCMap support to the CID driver.
* Add track kerning support to the Type1 and PFR driver and the API
(The degree of kerning, e.g. light, normal or tight, and
the glyph size has to be passed as parameter).
* Add kerning (AFM file) support to the CID driver.
* Possibly add support for reading PFM files.
* Is the anti-aliased glyphs feature of BDF also available in PCF format?
If yes, add support to the PCF driver.
