This can be used to store a texture at a different resolution without
having to change all of the metrics that reference it.
The most obvious use is to lower the resolution of large images.
A less obvious use is to raise the resolution of images. If an image is
going to be zoomed, it may be useful to store the texture at a higher
resolution than native.
This can be done with metrics, but it's a pain to have to track down
each metric that needs to be changed. This (should) also work with
fonts (but that needs testing).
Use this sparingly.
