X Border Attributes

XComposite, which is currently our only capture method for windows, doesn't handle X border width. This works in a lot of cases but anytime there's a border, a bug occurs where the lower right is clipped. 
This patch has two goals: 

1) To position and size the capture texture correctly in accordance to the border.
2) Adds a configuration option to allow people to toggle it (which in most cases will simply do nothing) with a default of not including it.

Just noting for future developers, this usage of ternary operator makes us sad pandas.

Use:
```C
if (foo) {
	bar1();
} else {
	bar2();
}
```
in the future.
