Why is the type unsigned int instead of TextAutosizingOverride?

[pdr., 2013/10/18 01:28:44]

This is a c++ issue where enum types can't be in bitfields but the casts work
out as an unsigned.

I've removed this line as pfeldman pointed out we can use the inspector
instrumentation instead of modifying settings.
