- * Scroll Method

-/* There are several methods fbcon can use to move text around the screen:
- *
- * Operation Pan Wrap
- *---------------------------------------------
- * SCROLL_MOVE copyarea No No
- * SCROLL_PAN_MOVE copyarea Yes No
- * SCROLL_WRAP_MOVE copyarea No Yes
- * SCROLL_REDRAW imageblit No No
- * SCROLL_PAN_REDRAW imageblit Yes No
- * SCROLL_WRAP_REDRAW imageblit No Yes
- *
- * (SCROLL_WRAP_REDRAW is not implemented yet)
- *
- * In general, fbcon will choose the best scrolling
- * method based on the rule below:
- *
- * Pan/Wrap > accel imageblit > accel copyarea >
- * soft imageblit > (soft copyarea)
- *
- * Exception to the rule: Pan + accel copyarea is
- * preferred over Pan + accel imageblit.
- *
- * The above is typical for PCI/AGP cards. Unless
- * overridden, fbcon will never use soft copyarea.
- *
- * If you need to override the above rule, set the
- * appropriate flags in fb_info->flags. For example,
- * to prefer copyarea over imageblit, set
- * FBINFO_READS_FAST.
- *
- * Other notes:
- * + use the hardware engine to move the text
- * (hw-accelerated copyarea() and fillrect())
- * + use hardware-supported panning on a large virtual screen
- * + amifb can not only pan, but also wrap the display by N lines
- * (i.e. visible line i = physical line (i+N) % yres).
- * + read what's already rendered on the screen and
- * write it in a different place (this is cfb_copyarea())
- * + re-render the text to the screen
- *
- * Whether to use wrapping or panning can only be figured out at
- * runtime (when we know whether our font height is a multiple
- * of the pan/wrap step)
