Issue Description

I am trying to use the align.m function to align video and depth streams using the MATLAB wrapper. I am using the code chunk suggested in issue #2455.

align_to = realsense.stream.color;
alignedFs = realsense.align(align_to);
.....
fs = pipe.wait_for_frames();
aligned_frames = alignedFs.process(fs);

When using this I get the following error message corresponding to the line of script.

alignedFs = realsense.align(align_to);

Can anyone help with this error message (see below)?

Error using realsense.align
Error: File: align.m Line: 9 Column: 35
A constructor call to superclass realsense.filter appears after the object is used, or after a return.

Error in acquire_color_depth (line 45)
aligned = realsense.align(align_to);

Hi AndrewFielding,

Besides the changes mentioned in #2455, you will need to do another change in align constructor.
Together 2 changes:
a) For https://github.com/IntelRealSense/librealsense/blob/master/wrappers/matlab/align.m#L8
Replace "this.objectHandle" with "out", which is used in next line for fitler().
b) As mentioned in #2455, comment out validateattributes() in process()
https://github.com/IntelRealSense/librealsense/blob/master/wrappers/matlab/align.m#L17

Thanks!
