Remarks

Especially if the survey lines do not run N-S or E-W, gridding parallel to the XY axes results in up to half the gridding area being dummies (padding), which is not only inefficient, but affects processes like filtering. This routine returns the rotated extents rectangle for a given gridding azimuth. The data is rotated CCW by the input azimuth. The N-S and E-W extents of the rotated data are determined and the bounding points rotated back by the input azimuth to locate the angled bounding rectangle around the input data. As with GetGriddingAzimuthToMinimizePadding_DU the extents are padded in each direction by 1% of the maximum height/width Operates on all selected lines.
