Keep Ratio Keyword

It is possible to add the keyword msx-keep-ratio to a background image URL (at any position) to keep the aspect ratio. By default, the background image is stretched to fill the entire screen. By adding the keyword, the image is scaled up/down to fill the entire screen. This feature is available since version 0.1.150.

Note: Because of the immersive mode (introduced in version 0.1.150), the aspect ratio of backgrounds is not always 16:9 (like in previous versions) but can have any aspect ratio. Therefore, this keyword should also be used for backgrounds with an aspect ratio of 16:9 if stretching should be avoided.
