1	n/a	"""TypeinViewer class.
2	n/a
3	n/a	The TypeinViewer is what you see at the lower right of the main Pynche
4	n/a	widget. It contains three text entry fields, one each for red, green, blue.
5	n/a	Input into these windows is highly constrained; it only allows you to enter
6	n/a	values that are legal for a color axis. This usually means 0-255 for decimal
7	n/a	input and 0x0 - 0xff for hex input.
8	n/a
9	n/a	You can toggle whether you want to view and input the values in either decimal
10	n/a	or hex by clicking on Hexadecimal. By clicking on Update while typing, the
11	n/a	color selection will be made on every change to the text field. Otherwise,
12	n/a	you must hit Return or Tab to select the color.
