GetTextDimensions
From King Arthur's Gold Wiki
Gets the dimensions of some text.
As this is GUI-related it is client only - it should be wrapped in "if ( getNet().isClient() )" or be in a client-only script.
This method is part of the GUI namespace so you need to prefix calls to it with 'GUI::'.
void GUI::GetTextDimensions( const string &in text, dimension2di &out dim )
