scripts: Add keymap-render.py script
Add a script for generating a png with the short-name (ignoring variants) of all keymaps listed by "localectl list-keymaps" pre-generated. This scripts also generates a ply-keymap-metadata.h file with info on which pre-generated keymap name is where in the png. This will be used in a follow-up commit to add support for a new keyboard-keymap-icon control to libply-splash-graphics. Note that this commit does not add the generated keymap-render.png file, this file will be added to each themes image-dir separately as the color of the pre-generated text may differ per theme. Changes by Hans de Goede: - Change generated metadata into a C header file - Drop drawing of curved corners, we just want the text - Add special handling for dvorak Signed-off-by: Hans de Goede <hdegoede@redhat.com>
