[BOOTVID_FONT_GEN]
Improve the bootvid font generator of Colin (see r70507) in many ways:
- Allow the user to specify the font name (optional), and optionally a font size and x-
and y-offset so that (s)he doesn't have to recompile the generator each time (s)he
wants to test a new font.
- The default settings (in case the user doesn't specify all or part of the font
definition) are those of Windows' bootvid font (i.e. "Lucida Console", font
size 10, x_offset = y_offset = 0).
- Create only once the DC and the font handle (to be used for all the generated
characters) instead of each time a character is being generated. I still keep the
recreation of the HBITMAP for each character (I don't know if we can also improve
there by creating it once and zeroing it out before generating each character).
