[Chameleon] textbutton label vertical align

[Godwin, Elizabeth]

I just came into this conversation at the end here, but I just wanted to
add an observation in case it has implications here...

When I moved my chameleon apps from windows over to linux (Red Hat) I
had to change my text button shared resource to add a nudge of 4.  The
lables were all offset upwards.  

Why would this happen across different machines?

Cheers,

Liz Godwin
