I just found one ANSI escape that is different in ANSI art and in Linux Terminal.
The problem is this ANSI Art https://16colo.rs/pack/blocktronics-b-sides/om%20-%20bjork%20-%20debut.ans
this is rendered as while in PabloDraw but it's blinking in Linux Terminal (part of the face), because
5 according to Wikipedia is "Rapid Blink" but it's also in MS-Dos it seems. But 47;30 is black background and gray color (color is named as white but it's gray in Wikipedia and Linux Terminal).
Anybody know why it should render as white? Is this some kind of exception? Is this documented somewhere? Are there any other things like this that should work differently than on Linux Terminal?
