Don't reset colorpairs in the middle of drawing Resetting colorpairs while drawing the mainwin causes the existing contents in a popwin to refer to invalid color pairs. We used to draw the mainwin first and redraw the contents of each window from scratch. Moving to libpanel in 1.6 changed this, so background colors occasionally bled into your popwin. This changes the colorpair logic to only trigger when we need to, and to forcibly dirty every window if needed. NOTE: if we don't have enough color-pairs to draw the current screen, this will draw everything twice. But it will probably almost never happen.
