1) OSD_FontManager returns bad list of X11 fonts, at least in my system
2) Anyways, even with the patch I posted in another post, OSD_FontManager will grab just X11 fonts, not
user installed ones, which are usually many, many more, at least on Linux systems.
3) In Opengl_togl_begin_layer_mode.cxx, there are *many* bugs and side effects :
---- call_togl_textsize2d as a side effect changes current font height; it's not possible
to query for a text string size without having to re-set the font height after on if the
used is different.
---- call_togl_text2d don't use height parameter; so a call without textsize2d would take a random height.
There are other bugs there, but I guess it's enough for now :-)
I think all that module should be refactored completely; it's one of the worst coded piece I've ever seen....
