4x8 Font

Thanks! Yes, I think those probably make more sense given the number of pixels. I'll add that font in now (as Font4x8Numeric)

For anyone who is interested in trying stuff like this, here's the code I used to make the font:

var font = ""+
    "### "+
    "# # "+
    "# # "+
    "# # "+
    "# # "+
    "# # "+
    "# # "+
    "### "+
    " #  "+
    " #  "+
    " #  "+
    " #  "+
    " #  "+
    " #  "+
    " #  "+
    " #  "+
    "### "+
    "  # "+
    "  # "+
    " ## "+
    "##  "+
    "#   "+
    "#   "+
    "### "+
    "### "+
    "  # "+
    "  # "+
    " ## "+
    "  # "+
    "  # "+
    "  # "+
    "### "+
    "# # "+
    "# # "+
    "# # "+
    "### "+
    "  # "+
    "  # "+
    "  # "+
    "  # "+
    "### "+
    "#   "+
    "#   "+
    "##  "+
    " ## "+
    "  # "+
    "  # "+
    "### "+
    "### "+
    "#   "+
    "#   "+
    "### "+
    "# # "+
    "# # "+
    "# # "+
    "### "+
    "### "+
    "  # "+
    "  # "+
    "  # "+
    "  # "+
    "  # "+
    "  # "+
    "  # "+
    "### "+
    "# # "+
    "# # "+
    "### "+
    "# # "+
    "# # "+
    "# # "+
    "### "+
    "### "+
    "# # "+
    "# # "+
    "### "+
    "  # "+
    "  # "+
    "  # "+
    "### ";

var fdata = "";
for (var col=0;col<font.length/8;col++) {
  var i = (col&3)+((col&~3)<<3);
  console.log(i);
  fdata += String.fromCharCode(
    (font[i   ]==" "?0:128)|
    (font[i+ 4]==" "?0:64)|
    (font[i+ 8]==" "?0:32)|
    (font[i+12]==" "?0:16)|
    (font[i+16]==" "?0:8)|
    (font[i+20]==" "?0:4)|
    (font[i+24]==" "?0:2)|
    (font[i+28]==" "?0:1));
}
// ...
 g.setFontCustom(fdata, "0".charCodeAt(0), 4, 8);

As it happens I forgot that the font data is column-ordered. If I'd originally made the characters at right-angles to where they are, the code for it would have been amazingly simple.
