Graphic3d_TypeOfData - added Graphic3d_TOD_FLOAT for passing single-float vertex attributes. Graphic3d_TOA_CUSTOM - changed value to increase the range for custom vertex attributes locations (to fit into hardware limits). Graphic3d_ShaderProgram::SetVertexAttributes() - introduced API for defining custom vertex attributes. For compatibility with automated wrappers: - Graphic3d_Buffer::Init() - added prototype taking NCollection_Array1<Graphic3d_Attribute> instead of C array - Graphic3d_IndexBuffer::InitInt32() - added typed initialization method. - Graphic3d_ShaderProgram::PushVariableVec3() and others - added typed methods to push uniform varibales.
