point size was previously only calculated based on the transformation matrix but now uses the transformation matrix, the rotation matrix and the font matrix values. the calculated value still seems unlikely to be correct so it is exposed using the page's experimental access for now, rather than as a public getter.
- begin adding support for extended graphics state (the 'gs' operator) including setting the font #39.
- apply page level rotation to the glyph bounding box and width to get correct glyph sizes #41.
- wrap page rotation in a value type to ensure the value is restricted to right angle rotations and provide convenience members #42.
- fix bug where system font finder never worked for truetype fonts because it began reading the file from the wrong offset.
- In the Letter class:
- Renaming 'Location' to 'StartBaseLine' and adding 'EndBaseLine' for better localisation of the letter ('Location' is also kept).
- Adding TextDirection.
handle "unionsq" and other tricky glyph names. log missing glyphs. ignore flexpoints in type 1 subroutines. improve system font performance and substitution. handle truetype fonts using standard 14 fonts.
temporary 'safe' untested implementation of seac for type 1 charstrings.
make structure public
bump version of package and project to 0.0.3 (it had accidentally increased to 0.0.5)
