Changing AngleOrPixelScalarQuantity to ScalarAngleOrPixel

[ysBach]

I recently found AngleOrPixelScalarQuantity is removed (d61630e).

This made my package to fail when I tried to import it (I used AngleOrPixelScalarQuantity to make custom aperture classes), so I need a fix.

Will everything be fine if I change AngleOrPixelScalarQuantity to ScalarAngleOrPixel, or do I need more?

Oh I have just found there are more changes in the internal API (_shape_params, etc)...

@ysBach Yes, you can simply replace AngleOrPixelScalarQuantity with ScalarAngleOrPixel. These descriptor classes (and also _shape_params) aren't part of the "public" user-facing API, so these changes aren't in the change log or undergo a deprecation period. I don't think very many people have made custom aperture classes. In fact, you are the first person I've heard to do this. Sorry for any disruption.
