patch to fix terminal-box's cernter image not corretly draw
This patch fixes the terminal-box's center image (background) not draw|update
when the terminal window's dirty area updates. This would cause a problem that
a (ugly looked) black background [1] would be displayed, if GRUB_BACKGROUND not
set an image background for it.
The layer would look sth like this
-- font's background (set by color_normal=while/black (black is transparent))
--
-- menu background (set by GRUB_BACKGROUND=) --
-- terminal-box's background (set in theme.txt, terminal-box:
"terminal_*.png" )
In other words, terminal_c.png would be displayed on terminal window as
background if not shadowed by menu's background and font's bg color is black.
The result would be a better look and consistency view as the background are
scaled correctly and seamless with it's decorations (compared with backgrounds
set by GRUB_BACKGROUND=)
[1] "black" is used as a transparent color (aka color key)
