* CC3VertexLocations
* CC3VertexColors
* CC3VertexIndices
* CC3VertexPointSizes
* replicated more foundation classes from core to legacy
* started port of CC3GLProgramMatchers (renamed to CC3ShaderProgramMatchers)
* started port of inbuilt multi texture shader CC3MultiTextureConfigurable from GLSL to HLSL
