Replaced some f64 by T in container classes, where computations were only f32 correct anyway.
Made triangle3d.isOnSameSide private as it is completely unrelated to triangles.
Renamed plane.existsInterSection to plane.existsIntersection since all other functions concerning intersections use the small s.
Fixed plane3d.classifyPointRelation to return the correct relation. Spotted by vitek.

Just trying the SVN out, fixed a bug in big endian conversion, that I’m been meaning to get someone to fix

More fixing of Sphere texture coords. Now we have proper spherical mapping, but a weird seam at the date line - when using the earth.bmp.

Another change for the hasMipMaps fix which was not committed last time. Fix for CsphereNode texture coords which now range from 0 to 1 on both axes.

Fix setResizeAble under Linux, which had the correct implementation as a private method. Also removed the dummy implementation from DeviceStub.
