Avih (of Firefox plugin "Smoothwheel" fame ;) ) worked on bringing back that extended GSdx information we lost in the merge to the new WX Gui.

Here's his changelog:

GSdx, PCSX2: Fixed broken GS info at the title bar
* If the plugin doesn't support the API, PCSX2 will display only the image mode (progressive/interlaced field/frame), NON i18n!
* If the plugin does support the API, PCSX2 will not display the image mode, and instead display the info from the plugin
* GSdx now properly sends title info: resolution, image mode, deinterlace mode (weave - bff, etc)
* To enable the full GSdx title info as it used to work before it got broken: uncomment //#define GSTITLEINFO_API_FORCE_VERBOSE at GS.h of GSdx.
NOTE: When using an older pcsx2.exe with newer GS plugin, the title would contain duplicate image mode info. All other combos work fine.
* PCSX2 still displays the performance info, etc in the title bar.

Thanks a bunch for bringing this information back, Avih! :)
