2018-03-09Explicitly mark helper methods that only operate on ASCII rangesRyan Harrison
A number of our character helper methods take in wide character types, but only do tests/operations on the ASCII range of characters. As a very quick first pass I am renaming all of the foot-gun methods to explictly call out this behaviour, while I do a bigger cleanup/refactor.

2018-03-08Convert Before{Selection|Value}Change to return a boolchromium/3366dan sinclair
Both of these IPDF_FormNotify methods return {-1, 0, 1} but all callsites only care about < 0 and >= 0. Convert to return a bool that treats the 0 and 1 case as the same. This also makse sense in terms of the API because false means validation failure. The case where 0 was used was a place holder for we didn't try for this field type, which also implicitly means validation passed.
