The compositor IPC path transports transform matrices as LibGfx values, so the matrix type should own its byte representation. Add the FloatMatrix4x4 specialization in a new LibGfx source file and serialize the fixed-size float array directly through the IPC stream. This is preparatory work required to add IPC between the main and compositor threads.
