- Only load the thumbnails that are currently visible in the window
- Unload thumbnails that are leaving the visible area
- Much less memory needed, but scrolling is now slower
- This also unintentionally fixes issue #86

It is therefore not needed to check a passed pointer before this function call.
A corresponding update suggestion was generated by the software "Coccinelle"
from the following semantic patch approach.

- Buffer for window content is bigger than the window, minimizes artifacts
when window is resized
- Back to using XSetWindowBackgroundPixmap() instead of XCopyArea(),
no need to handle exposure events; X server can show gray background directly
after resize event before sxiv redraws the window contents
The default prefix key is C-x, and can be changed in config.def.h. The
first key pressed after the prefix key will be passed the external key
handler, unless the key is Escape, which is used to cancel the prefix.
- Command it_toggle_image_mark (bound to 'm') toggles mark of current
image
- Command it_navigate_marked (bound to 'N'/'P') can be used to go to
the next/previous marked image
- When option -o is given, all marked files get printed
