Change from dimension2d<s32> to dimension2d<u32> where practical. IImage and ITexture now have unsigned dimensions, as does screen size. This has had a significant knock-on through the code base, but it is more technically correct - the BEST KIND of correct.
GUI elements and draw2DImage methods still have and take signed dimensions, but we can look into this in future. Regression tested with the test suite and the example apps. Note that createDevice() now takes dimension2d<u32>!

Change ray/bounding box selection so that the nearest node is determined by the actual collision point with the bounding box (or the distance to the box centre if the ray starts inside the box). Since this is a functional change from the old behaviour, I'm only committing to the trunk. This will be slightly slower than the old method, but should return the correct node; I consider accuracy to take priority over efficiency for collision.
tests/sceneCollisionManager.cpp has been updated, as has examples/07.Collision/main.cpp.

Partial fix for CSceneCollisionManager::getPickedNodeBB(), but we should push on and do a proper test for the actual intersection point with each hit cube.

Also clarified the comments on ISceneNode::setVisible() and isVisible(), and added a new method, isTrulyVisible() that recursively checks any Parent nodes as well.
Unit/regression tests updated, verifying that they tested (and failed) with the old behaviour and pass with the new.
