The Imagine style is based on image assets. The style comes with a
default set of images, but the images can be easily changed by
providing a directory with images using a predefined naming convention.

[ChangeLog][Controls] Added the Imagine style, which is based on
image assets that can be provided using a predefined naming convention.
