	TODO (2204B)
	---
	1 + optimize redraws (redraw only the modified rectangle)
	2 - add screen geometry option (-g 25x80?)
	3 + implement trapezium
	4 - implement ellipse
	5 - (?) filled box (B)
	6 - (?) manage filled box character (as for other styles)
	7 + parse control characters
	8 + parse arrows (text-mode will allow movements as well)
	9 - (?) implement CTRL+G as abort (aside ESC)
	10 - (?) remove extra blanks until EOL when saving to file
	11 - manage special chars (DEL/CANC) during text insert
	12 (also do not print unmanaged chars!)

	14 - catch SIGWINCH and react appropriately (after scrolling is
	15 enabled)

	42 * auto-arrow 'A' (automatic end-char)
	43 * move configs in config.h
	44 * get screen geometry
	45 * allow the use of [ENTER] to confirm arrow, boxes (useful
