Subject: Avoid use of math.h

  To update the generated source file, first build the converter:

      $ gcc -O2 -Wall framebuffer/convert_font.c \
          -o build-Linux-framebuffer/tools/convert_font

  And then use it to generate the souce file:

      $ build-Linux-framebuffer/tools/convert_font \
          framebuffer/res/fonts/glyph_data \
          framebuffer/GEN_font_internal.c
