Added tests to check whether the driver supports the necessary features, and stop early if it does not make sense.
Fixed line endings for testXML.cpp

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>!

Merge fix for CTerrainSceneNode::preRenderLODCalculations() to trunk; take the camera's up vector into account when determining whether terrain scene node visibility needs to be rechecked. New test added; thanks to Travis for another great test case.
