Add more features, bug fixes and bugs ;-) Most notably: - Reflow is now working. Terminal size will fill the window and cols/rows will be resized/calculated based on window and font size. - Added support for different fonts (i.e. bold, italic, bolditalic). - Enabled blinking characters. - Adde more tests and caught a few subtle bugs. - Removed renderer code (which was part of xterm.js) and just doing naive rendering in terminal.gd, but it seems to perform a lot faster. Still not working completely: - vim (some weirdness going on). - vttest (more weirdness). Todo: - Fix the above. - Draw the cursor! - Improve performance. Performance is still not great. The terminal becomes unusable when running `yes` or `cmatrix -r`.
