Bug#495754: grub-pc: Support for screen resolutions other than 640x480 is not simple enough

[Olaf Mandel]

Package: grub-pc
Version: 1.96+20080724-8
Severity: wishlist
Tags: patch

On some computers the screen display is not scaled if operated on a low
resolution. Instead, the image is simply displayed smaller. It should be
made easy to change the resolution that grub expects (defaults to 640x480).

The resolution could be encoded in a variable in /etc/default/grub, e.g.
GRUB_GEOMETRY. If the value of this is changed, the background picture
might become unusable. Therefore it is necessary to create one if the
picture in this resolution was not present before. Took the command
(rsvg) for that from bug #465087.

Missing in patch:
* Clean up unneeded automatically created pictures in 05_debian_theme.
* Automatically detect the correct panel resolution in update-grub.
