report [#34772] Incorrect aspect for tex mapping from camera view

Browse Source 
There was no good way to UV project from a camera with non-square view-border without it stretching the image (even using 'Correct Aspect').

While this isnt a bug its useful to do a UV projection without stretching the image, added 'Camera Bounds' option.
