Summary0000284: Cache font objects in every control
DescriptionWhen changing to the EmbeddedFont structure in the 0.5.1.0 version, I forgot to cache the font objects. This has an impact on CPU for updating song position because the OnPaint event is called every 10ms (see related issue).

Comment:
MPfm 0.5.2.1
- Added a font cache to every control. This further optimizes CPU usage when refreshing the UI often.

A further optimization could be to share the font resources between instances of the controls, but I'm not sure if this is possible.
