I was expecting this too, but on my system the size of the rendered text do not
change, i have write this few lines
to check this behaviour:
#include <cstdlib>
#include <FL/Fl.H>
#include <FL/Fl_Double_Window.H>
#include <FL/fl_draw.H>
class mywin: public Fl_Double_Window {
public:
mywin()
:Fl_Double_Window(10,10,320,200)
{
}
virtual ~mywin(){}
virtual void draw(){
fl_color(255,255,255);
fl_rectf(0, 0,320,200);
fl_color(0,0,0);
fl_font(FL_COURIER,49);
fl_draw("courier",40,40);
}
};
int main(int argc , char** argv){
if(argc>1){
Fl::visual(FL_DOUBLE|FL_INDEX);
Fl::set_font(FL_COURIER, argv[1]);
mywin w;
w.show();
Fl::run();
}
std::exit(0);
}
if you compile this source will be possible to check of the font changes, for
example:
./test -*-courier-medium-r-*-*-*-*-*-*-*-*-*-*
give a fixed font size even if we are forcing to draw the text with a size of
49 but if you do:
./test courier
on my system all works fine...

I will check the library source but i do think i have not enought experience to
figure out how it works.
Bye!
