Optimize the X stuff a LOT...

1) Only redraw the individual chars that changed, not any line with a char
that changed
2) When and Expose event or GraphicsExpose event happens, only redraw the
affected rectangle (Previously, it redrew the entire screen for every
exposure)

Make the window slightly resizable... integer scaling only (ie: 1x or 2x)
Currently, will only go up to 2x... if anyone can dig up an open-source
function to do integer-only scaleing of XBitMap (XBM) files or images, I'll
be able to increase this easily enough... but 1280x800 should be enough for
anyone... *snicker*
