New constants and use of Float32Arrays
* `ColorMatrix._matrix` and `_data` are now Float32Arrays. * Calling the `ColorMatrix.set`, `reset` and `getData` methods all now use the built-in Float32 Array operations, making them considerably faster. * `ColorMatrix.BLACK_WHITE` is a new constant used by blackwhite operations. * `ColorMatrix.NEGATIVE` is a new constant used by negative operations. * `ColorMatrix.DESATURATE_LUMINANCE` is a new constant used by desaturation operations. * `ColorMatrix.SEPIA` is a new constant used by sepia operations. * `ColorMatrix.LSD` is a new constant used by LSD operations. * `ColorMatrix.BROWN` is a new constant used by brown operations. * `ColorMatrix.VINTAGE` is a new constant used by vintage pinhole operations. * `ColorMatrix.KODACHROME` is a new constant used by kodachrome operations. * `ColorMatrix.TECHNICOLOR` is a new constant used by technicolor operations. * `ColorMatrix.POLAROID` is a new constant used by polaroid operations. * `ColorMatrix.SHIFT_BGR` is a new constant used by shift BGR operations.
