When pressing Tab to move to the next input in the same block (and Alt-Tab to move backward), we currently skip buttons that have the UI_BUT_DISABLED flag. This PR makes these operations also skip buttons that have UI_HIDDEN. This makes tabbing work better in places like the color picker where we show/hide the RGB and HSV buttons depending on mode.
