TEXT8X8 and TEXTVGA bitmap formats

[anthonysavatar]

I was playing around a bit with the TEXT8X8 bitmap format and made a little serial terminal emulator.

github.com/AnthonyDiGirolamo/blackice_gameduino_terminal

Each line of text is drawn as a single bitmap of 60 characters. 34 lines fit on the screen.

I'd like to add TEXTVGA mode too. That would use two bytes per character instead of one but then I could add vt100 escape sequence support for colors. I'm assuming the data format for TEXTVGA mode is the same as described here:
en.m.wikipedia.org/wiki/VGA-compatible_text_mode#Data_arrangement

It might be nice to add support for drawing text using these formats since it takes up so little ram. I'll try to make a pull request when I get the hang of both formats.

Here is a video demo:

That is brilliant! Yes TEXTVGA is in the "legacy" arrangement with a color attribute byte for each character.
