Additional spinner size (24x24)

Question

There is an open issue around aligning icon-sizes (https://gitlab.com/gitlab-org/gitlab-ce/issues/62609).

Essentially a medium-sized spinner 32x32 is used next to other icons that are 24x24.

The goal is to have all icons be of the same size.

Since the currently supported spinner sizes are 16x16, 32x32 and 64x64 the only option I can see at the moment is to increase the size of the other icons to 32x32.

Unless we can add support for 24x24 sizes for the spinner?

Not sure if that is an option but trying to get all the input I can get on this 👍
