Fixes to make VBOs actually work in OpenGL. Need more improvements, though. Minor fixes in other files.

-so far only the openGL driver is supported, will add dx tomorrow or the next day

-right now to use, go: MeshBuffer->setHardwareMappingHint(EHM_STATIC); but this will be automatic when complete

-code needs a clean up, and the design isn't fixed, I just wanted to get stuff happening :)

-works well with hardware skinning :)

passing arrays were not working, can an openGL programmer check this is now right?

-let the user add a shader without a pixel or vertex shader, as docs state.

Make use of core::IdentityMatrix. Removed some redundant or unused code. Some minor reorganizations.

right now this only disables software skinning so that hardware skinning can be done externally

-fixed bug with joints being one frame off updating their AbsolutePositions when transiting, pointed out by shogun

-optimized CSkinnedMesh::buildAll_LocalAnimatedMatrices()

virtual void OnSetMaterial(const SMaterial& material) { }

to IShaderConstantSetCallBack, so the callback is able to set constants based on the properties of the used material.

-fix in:
bool CAnimatedMeshSceneNode::removeChild(ISceneNode* child)
found by ssexton

-added requested getJointCount() in AnimatedMeshSceneNode, which simply calls getJointCount on the held mesh

-added CSkinnedMesh::isStatic()

Changes in version 1.4 (... 13.11.2007)
- Fixed somed CQuake3ShaderSceneNode problems.
- Changed BurningsVideo internal Vertex Format. version changed to 0.39
- SceneManager:
   Removed the seperate rendering states for quake3 Shader Scene Nodes.
   Nodes are now solid or transparent. ( but still more states are needed )
