Fix some issues discovered by some PDF checking tools:
...
- Extremely small floating point numbers would be written with exponential
notation my the pdfioContent functions. They are now written with up to 6
decimal places of precision with excess trailing 0's removed.
- 8-bit (simple) TrueType fonts were embedded without a Widths array, which
made Acrobat Reader sad but nobody else...
- Switched to using the WinANSI base encoding, which is CP1252.
