Add reference perspective overlay to Icon-O-Matic.

I might be helpful to add the option to toggle a reference layer that shows the default perspective as illustrated in the Icon Guidelines: https://www.haiku-os.org/development/icon-guidelines
This way we could more easily ensure that we're at least staying close to a standard perspective (and thus hopefully avoid issues like #8747 in the future).
This could be toggled on and off, possibly have its opacity easily altered, and be able to choose whether or not to be shown above or below the other layers.
I created an icon very close to the "reference" image from the Icon Guidelines, but in doing so it raised another question. As you'll see from the attached image, the top perspectives and even shadow perspectives on the two cubes differ.
While comparing that reference icon to other "official" icons, such as the App_GLDirectMode2 icon, it seems pretty clear to me that the reference image has a higher back-end. The App_VirtualBox icon shares the low back-end with the GL one... but other icons like the App_MediaConverter seem to have an even higher back-end angle than the reference image.
How important is it to stick to the reference angle?
If we do add such an overlay to help us "get it right" in the future, which angle should we go with as the default? The slightly higher top/back of the reference one with less perspective on its shadow... or the slightly increased perspective look of the GL / VirtualBox cube icons (with the lower top/back and the shadow that's slightly thicker up front and narrower in the back)?
