A simple sample .cvx file, not compressed

"Canvas" illustration software from ACD Systems allows the free combination of vector, image, and text objects with high precision (equivalent to a CADD or GIS program) on multiple layers and multiple pages. It has a unique file format that is not documented, and may or may not be compressed in any given instance. 

LO/OO Draw is the only program I've seen that seems to have a similar structure with multiple layers and the ability to use multiple object types relatively freely. It would be useful to have an alternative to Canvas for when the older versions no longer work in newer Windows (also formerly in Mac but no longer works). Is there a way to reverse-engineer the .cvx format (no documentation) to at least be able to open it in Draw (then save in an ODF format of course? Certain obvious restrictions might be reasonable, such as only uncompressed files (so you can read the file structure whatever it is).

A simple sample file is attached with a few typical objects and text on a single page and layer. Things can get much bigger and more complicated.

BIPU support added to OleToy.

r.e. is doable, hard to predict how many file would be required for reasonable result.
