wintab: lcOutExtX and Y values are not initialized

[Eriks Dobelis]

This is one of the patches to fix 
http://bugs.winehq.org/show_bug.cgi?id=18517 and enable pressure 
sensitivity in Photoshop CS4+

Values of lcOutExtX and lcOutExtY are currently initialized to 0. Some 
software (e.g. Photoshop CS4) gets confused and does not change the 
values. lcOutExt? values are used in scaling x and y values, which means 
they are afterwards scaled to 0 in all packets.

If lcOutExt? values are initialized then Photoshop CS4 changes the 
values during opening of the device, and afterwards x and y are set to 
usable values in packets.
