3b2000c2bf doc/scaler, swscale/options: use proper capitalization 
Proper names should be capitalized in all user facing API as far as
possible. The option names themselves have not been changed since:
1. We consistently keep option names in lower case.
2. Changing them would break existing scripts.

The converse is also true: improper names should not be capitalized
generally.
