Remove the SetRenderingListType() function from HYP_Mesh lib.

[::Release 1.10.0 - 2006/10/05::]

Change: slightly improved host-API speed by removing some valadity checks (HYP_Object, HYP_Camera, HYP_GPUShader, HYP_Input, HYP_VertexPool, HYP_Scene and HYP_Mesh). So you have to check yourself the correctness of the functions's inputs.
Change: improved the working of FBO (framebuffer object).
Bugfix: in GetFaceNormal() and GetFaceCenterPosition() of HYP_Mesh. These functions returned bad values.
Bugfix: in HYP_Mesh.VBQuad_SetQuadVertexPosition() and HYP_Mesh.VBQuad_SetQuadVertexColor(). Now vertex buffer objecdt is correctly updated.
Bugfix: in HYP_Mesh.CastRay() function. Now returns results correctly.

Remove the npotd attribute of check_hardware_caps element (scene node).
Feature: support of NPOT dimensions regular textures. This new feature is different than the npot texture rectangle previously added since NPOT regular texture can use normalized texture coordinates and support all regular texture features.
Change: now the HYP_Mesh.GetElevation() returns two values: the face elevation and the face index.
Bugfix: in floating point textures for NV arch. Now the internal pixel format is GL_RGBA_FLOAT32_ATI instead of GL_FLOAT_RGBA32_NV. This works fine with NPOTD texture rectangles and regular POTD textures. I don't know why but floating point textures is still a real pain!
