Keys:
* With "Hotkeys" selected and main box focused: [1]-[7] draws one block (inserts one at a time, or over whole selection).
* With image origin/size boxes focused: [up]/[down] changes value by ±5, [pgup]/[pgdn] by ±20, [enter] applies typed value.
* Normal undo functions seem to work fine for the main text area, but copy/paste your progress to a .txt file regularly.
Done:
* Spam warning
* Don't overwrite newlines with insert/fill
* Magic box filler (Generate blank grid to fit image)
* Checkbox to keep cursor still
* Custom palette handy for mapping to numeric keypad
* Two types of rotation
Todo:
* Set up arrows to move origin or size corners rather than just fields?
No restriction. WTFPL.
