Bugzilla #45342:
AFP Fonts: Fixed interpretation of metric for fonts with fixed metrics and made sure all repeating groups in FNP (Font Position) are processed.
Submitted by: Emil Maskovsky <styryx.at.seznam.cz>

Modifications to patch by jeremias:
- Style changes (tabs, variable names, javadocs)
- Fixed handling of spaces in URLs (as in IF branch)
- Modified the way the metrics are calculated (Emil's solution didn't produce the values required by FOP)
