#1021 cocoa SCI_POSITIONFROMPOINTCLOSE returning invalid position

[Todd Whiteman]

On Cocoa (i.e. ScintillaTest) when the scintilla editor is vertically scrolled (e.g. past one page), that SCI_POSITIONFROMPOINTCLOSE always returns "-1", whilst SCI_POSITIONFROMPOINT still returns the correct position.

Here's the simple modifications I was using to test this:

  ButtonMoveWithModifiers(ConvertPoint([event locationInWindow]), TranslateModifierFlags([event modifierFlags]));

It wasn't converting back out of scroll view coordinates.
