pub enum ContentMode {
ScaleToFill,
ScaleAspectFit,
ScaleAspectFill,
}
Rules for how content should stretch to fill its bounds
Stretches content to fit its bounds exactly, breaking aspect ratio as necessary.
Maintaining aspect ratio, content grows until it touches its bounds in one dimension.
This is the default ContentMode.
If the aspect ratio of the bounds do not exactly match the aspect ratio of the content,
then there will be some empty space within the bounds to center the content.
Maintaining aspect ratio, content grows until both bounds are met.
If the aspect ratio of the bounds do not exactly match the aspect ratio of the content,
the content will overflow one dimension of its bounds.
