Re: [PATCH v2 0/1] MR7091: windowscodecs: Make values returned from CanConvert consistent

[Jeffrey Smith (＠whydoubt)]

Windows supports conversion _from_ 34 formats.  It will convert _to_ those same formats, plus 1 other.  Of those 1190 combinations, all are supported.

Wine is far more sporadic.  It supports conversion _from_ 13 formats.  It will convert _to_ 23 formats.  Of the 299 possible combinations, 189 are actually supported.

I'm considering re-working the tests.  Rather than creating large todo lists, instead check the number of _from_ formats supported by each _to_ format, or something along those lines.
