This commit filters draw-calls based on the currently bound material index.

in BufferGeometry's drawcalls.

WebGLRenderer: Deprecated supportsFloatTextures(), supportsHalfFloatTextures(), supportsStandardDerivatives(), supportsCompressedTextureS3TC(), supportsCompressedTexturePVRTC() and supportsBlendMinMax().
