%IMGROT	Rotate an image
%	y=imgrot(x,angle) rotates the image x with angle radians
%	counterclockwise. The resulting image is large enough to avoid
%	clipping the corners of the input image. The operation is
%	approximately twice as fast as the standard Matlab command imrotate.
%
%	y=imgrot(x,angle,'crop') makes the output the same size as the
%	input.
%
%	y=imgrot(x,angle,'symmext') extends the rotated image symmetrically
%	(useful for fitlering etc.)
%
%	y=imgrot(x,angle,'crop','symmext') combines the two above operations.
