What exactly are the gfx_Get(RIGHT_POS) and gfx_Get(BOTTOM_POS)
supposed to return? Regardless of what image from a whole
variety of sizes I just displayed with file_Image(), I keep getting
132 and 136 respectively as the X and Y answers, which I suspect
might be the addresses of some intermediate variables they use or

The interim workaround is to keep track of my own image dimensions
in a DATA table, but you can see how klunky that could get...
