Look for Indiepath Render2Texture.
Drawing directly Texture onto Texture is possible through pBuffer and other ways but you have to implement that on your own (if only opengl is of interest, Indiepaths module will work, just rip the DX part out thats broken due to the rewrite of the DX module in mid 1.24)
Reason is that Max2D is OpenGL 1.2, anything to draw onto is at least an Extension (-> pub.glew) and OpenGL 1.3
