* src/font-view.c (draw_text): move text drawing into separate
function.
(create_text_pixmap): handle bitmap fonts by drawing the test
string at the correct size(s).
(add_face_info): display some information about the font.
* src/font-view.c (main): change so that it renders the text at a
number of different sizes, like fontcarton did. Need to show some
info about the font too ...
