Hello there

This is my first project with NGUI and I'm really enjoying it so far!
I have a little trouble however with anchoring labels the right way so the font sizes will stay the same on different screen sizes.
For example I have 3 buttons next to eachother with each a label attached. The way I've done it so far is put the overflow on ShrinkContent and the fontsize to 40, so that on a big screen the text will still keep its proportions. I've anchored the labels in a way that really hugs the text inside of it.
When i resize the screen however, it can happen that one of the texts increase in size before the rest. This looks pretty bad especially when these buttons are so close you can easily compare them.
Is there an easier or better way to get this working correctly?
