General usplash theme information

usplash supports multiple resolutions in one theme (generally using backgrounds of different sizes).
usplash also supports drawing a progress bar...but the progress bar can be any type of image.
the usplash theme can draw a suitably sized solid-color box on demand for user input/output, so a part of the screen generally needs to be reserved for this.

During lengthy processes, such as fsck, and "indeterminate" progress bar can be shown:

It would be very cool to have the same background in usplash as in GDM
it would appear as if the boot first takes place and the login box appears on top of the existing background once the boot has progressed far enough
The only discontiuity is the vt-switch from usplash to gdm...reducing it would probably be a post-Etch issue (this is not a usplash, gdm, or artwork issue, this is a driver issue, only with modesetting support in-kernel would this work)

To have a partially transparent progress bar and making it more and more opaque as the boot progresses (alpha-blending is not supported, usplash images use an indexed palette).
