Stefan 9cdb10d52e gnu: grub: Allow a PNG image and replace "aspect-ratio" with "resolution". ... * gnu/bootloaders/grub.scm (<grub-image>): Remove this record and replace it by ... (<grub-theme>)[image]: ... this field with the default from %background-image, (<grub-theme>)[resolution]: ... this field with the defaults from 'width' and 'height' of 'grub-background-image'. (<grub-theme>)[images]: Remove this field. (svg->png): Rename to ... (image->png): ... and use 'copy-file' instead of 'svg->png', if the suffix of the image file is not ".svg". (grub-background-image): Remove the arguments 'width' and 'height'. (grub-theme-image): Add function. (grub-theme-resolution): Add function. (grub-theme-gfxmode): Add function. (grub-image): Remove function. (grub-image?): Remove function. (grub-image-aspect-ratio): Remove function. (grub-image-file): Remove function. (grub-theme-images): Remove function. (%default-theme): Remove variable. (%background-image): Remove variable. Using image formats different to SVG was not possible. For a <grub-image> to be chosen, the 'aspect-ratio' of it had to be 4/3, as the resolution of any image was defaulting to 1024 x 768. There was no code to determine the proper boot-resolution to make any use of a list of images with different aspect-ratios. It seems to be a better solution to only define a single image with any format, and use a given resolution only for the conversion from a SVG file. This also makes the use of a special <grub-image> record unnecessary. Moving the default values from '%background-image' and '%default-theme' into <grub-theme> makes a customisation easier without (inherit) and allows to remove the undocumented variables %background-image' and '%default-theme'.
