* | doc/scaler, swscale/options: use proper capitalizationGanesh Ajjanagadde2015-10-10
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | all: add _DEFAULT_SOURCE locally wherever neededGanesh Ajjanagadde2015-10-04
| | | | | | | | | | | | | | | | | | Glibc 2.20 onwards generates a deprecation warning for usage of _BSD_SOURCE and _SVID_SOURCE. The solution from man feature_test_macros is to define both _DEFAULT_SOURCE and the old macros. This solution is on the lines of the one in commit af1818276ef271af98e2e2bbabb4dc875b4fa7d8.
