Perhaps one needs to get into the nitty gritty of *when* an object is
treated a PNG by Rev, but regardless:

1) if you import a GIF, you can assign both its image/alpha data to another
image by referencing its text

2) if you create a native image object within Rev, you can assign both its
image/alpha data to another image by referencing its text

I've heard that when working images in Rev, some things happen under the
hood at some point that cause Rev to treat images as PNG regardless of
whatever format they started as.  So Trevor's explanation may be
*technically* true, in that Rev treats ALL objects as PNGs.  But for
practical purposes, the text property does indeed reference both
image/alphadata.
