Tim Starling requested to merge work/tstarling/RotationMatrix into main Aug 12, 2024

Add a RotationMatrix class
Move the computation of the matrix to ViewDirection
In ViewDirection, calculate hfov and vfov before loading the input image, since this will be necessary for a future cropping feature.
Stop rounding views down to the nearest 8 pixels, that's a Pannellum tiling requirement not relevant here.
To compare ViewDirections with different invert properties, compare the rotation matrix elements.
