Fix applying filters directly to clips.
Style cleanup.
Workaround filter menu not closing on losing focus on OS X.

On OS X, clicking on a QuickView outside of the filter menu does not
cause the filter menu window to lose focus. Therefore, it does not close
as expected. The workaround is to add a right-aligned close button - but
only on OS X.
Do not capitalize all words of tooltips in new filter menu.

Our convention for tooltips is to use phrases and not capitalize each
word and not require a full sentence with ending punctuation. This is a
predominant convention.

Fix regression in commit 9d63be651.

filters were distorting the chroma planes with GPU processing enabled.
However, this problem affected all filters.
Revert "Fix regression in commit 9d63be651."

This reverts commit 2ec21bd41efca4b9e6ecb6f76bc3ce5f7c9ab799.
