System variables defaults and ranges

[DomCR]

Hello @DomCR. With the changes made in the commit 307819c34cc5f48f3e196bfdd24f451ea5080e46, the Autocad Application can open the created file as it should.

But in BricsCad, there is still a warning:

Running the RECOVER command, on BricsCad, it makes a valid file, but the image object seems to be removed.

Command:

RECOVER

BricsCad Prompt:

Can you take a look at this? Or the goal would be just Autocad compatibility?
