Subtle tweaks to scrollbars and popovers to add contrast and cleanups

David mentioned something about popovers sometimes having blurry arrows, so I figured I'd try to clamp down some coordinates just in case. I can't really tell if anything changed. Will need him to verify.

Got rid of +new usage, replaced with alloc/init. I know it doesn't really matter, technically, but it seems like 100% of Cocoa old timers prefer alloc/init. I'm kind of surprised they don't depreciate +new. *shrug*

Important tweaks to UIButton's layout logic. Getting pretty close to having it work the same way, I think. All that remains is to figure out what it does with the edge insets for titles and images, but I don't think I need that right now.

Some more tweaks to button sizing. This is surprisingly complicated. I think maybe the insets work right now, too.

Adjusted buttons based on the now (I think) correct UIButton layout behavior.

Trying to keep the arrow from being on a pixel edge.. again...

Additional contrast to popover graphics

The real UIButton appears to clamp the right edge to the contentRect's right edge. So.... now I am, too!

git-svn-id: svn://dev.iconfactory.net/Projects/Software/UIKit/trunk@4107 d3437ac4-8b1b-0410-be28-b75ab53cb89f
Even more tweaks. Feeling decent about this now, though.

Cleaning up the code.

Initial attempt at the new scroller style.

git-svn-id: svn://dev.iconfactory.net/Projects/Software/UIKit/trunk@4112 d3437ac4-8b1b-0410-be28-b75ab53cb89f
Removed missing files.

git-svn-id: svn://dev.iconfactory.net/Projects/Software/UIKit/trunk@4113 d3437ac4-8b1b-0410-be28-b75ab53cb89f
And another one... sigh.

git-svn-id: svn://dev.iconfactory.net/Projects/Software/UIKit/trunk@4114 d3437ac4-8b1b-0410-be28-b75ab53cb89f
A couple tweaks.

Tweaked default buttons for popovers

Attempting to make the stroke on the default scroller type a little stronger.

git-svn-id: svn://dev.iconfactory.net/Projects/Software/UIKit/trunk@4123 d3437ac4-8b1b-0410-be28-b75ab53cb89f
More adjustment. The problem is the stroke is done centered on the line which doesn't really line up with actual pixels. Setting 0 seems to let it decide what to do based on device. Whatever. David says it's good enough but maybe a tiny bit blurred. I *think* maybe the correct thing to do is apply a transform to the path of like, 0.5, 0.5 or something and then it might line up on actual pixels. But that'd have to be carefully done incase the path itself has 0.5s in it's own coordinates... bah.

Subtly tweaked the animation a bit. It felt like the left button items moved too much. Now they seem to fade out right about the time most of the button hits the center, and just about the same time when the title slides in there.... it's pretty neato.
