Fixes #419.

I thought that was the most logical place to "break the loop" too, but was concerned about the potential consequences since TagDescriptor is such a "generic class".

The String return values in TagDescriptor.getLightSourceDescription and ExifDescriptorBase.getWhiteBalanceDescription are close but not identical. Should probably decide which set to use.

Eventually, the ones in TagDescriptor will go away if PanasonicRawWbInfo2.GetWbTypeDescription is reviewed. I personally think the ones in TagDescriptor are mildly better.

heh - scratch all of that comment. I should read all the commits since you already made the choice in the last one.

It's still true that PanasonicRawWbInfo2.GetWbTypeDescription could probably get the same treatment and then getLightSourceDescription can be removed entirely.

return getWbTypeDescription(tagType);

getLightSourceDescription can be removed entirely

Thanks! I completely missed that.
