rewrote InterpolationTest

- added time marker in the graph
- added ability to change duration using ctrl + scroll
- path is now drawn
- doesn't need any assets
I know this isn't of any importance, but I had to rewrite it anyway, so I added a few things.
Update InterpolationTest.java
replaced generated assets with test assets
fixed stupid NPE

Skin was local

Bullet, small changes
Update custom mouse cursor image support.

The Windows operating system has the additional requirement for a custom
mouse cursor image to have a width and height that are both
powers-of-two greater than zero (not necessarily equal).

Update the documentation of the setCursorImage method in the Gdx.Input
interface to add this requirement.

Update the setCursorImage method to throw a GdxRuntimeException if the
width or height are not both powers-of-two greater than zero.

Improve exception messages that occur when a hotspot param passed to
Gdx.Input.setCursorImage is outside the bounds of the image represented
by the pixmap param.
