Basically, I replaced all methods in the font_metrics namespace by a proper virtual interface FontMetrics. The FontLoader is _the_ container for FontMetrics.
This patch should also bring some optimizations in a number of place in the code. This is because we do not need any more to search for the LyXFont at each font_metrics call. In effect, the speed advantage is not as sensible and this is a bit deceiving considering that this was my primary motivation behind the patch. But I like the patch anyway as it cleans up the relation and interfacing between fonts, metrics and frontends.
* frontends/FontMetrics.h: new virtual interface. Renamed from font_metrics.h
* qt4/GuiFontMetrics: corresponding qt4 implememtation. Renamed from qfont_metrics.C. The smallCaps particular case treatment has been transfered here as well as the width cache for MacOSX and Windows.
* qt4/QLPainter.C: the smallCapsText has been reworked to return the width of the drawn text.C
all other files: replace font_metric helper function call with corresponding FontMetrics method calls.

* frontends/FontLoader.h: new interface class.
* frontends/Application.h: new FontLoader() pure virtual method
* frontends/lyx_gui: update_fonts() and font_available() methods deleted
* [qt3/qt4/gtk]/GuiApplication: implement the new interface
* qt4/GuiFontLoader:
- renamed from FontLoader
- now derives from FontLoader
- now in the lyx::frontend namespace
* qt3/qfont_loader
- now derives from FontLoader
* gtk/xftFontLoader
- now derives from FontLoader

My goal is to transfer all of "frontends/*/lyx_gui.C" to "frontends/lyx_gui.C". When this is done, "frontends/lyx_gui.C" can go altogether as its functions will then be replaced with direct calls to theApp->XXX().
* frontends/lyx_gui.C: new file with code transfered from [qt3,qt4,gtk]/lyx_gui.C
* frontends/Application: 3 new font related pure virtual methods
* [qt3,qt4,gtk]/GuiApplication: implement the above method with code transfered from lyx_gui.C

These font related functions were identical for qt3 and qt4. They are not Qt dependent at all and could also apply to an eventual Win32 or MacOSX gtk port.
Jen-Marc says: It would be nice to convince fontconfig to do the same for linux.
