DECCRA documentation is incorrect
@chpe I'd assign this to you if you don't mind :)
We don't implement DECCRA
but we have a chunk for that with documentation. The parameters there seem to be incorrect.
The second rectangle should be specified by only 2 rather than 4 coordinates, to guarantee that it's the same size as the source. Source and destination pages should be present as parameters.
At least DEC STD 070, ek-vt520-rm.pdf and ctlseqs agree. I'm not sure where the wrong version came from, or whether some other similar escape sequences are also affected.
