- Differ the coordinates between 16:9 and 4:3,
can add a setting with a "w" as prefix
(e.g. sdcard_coord = 163,395 for 4:3
and wsdcard_coord = 170,395 for 16:9).
Isn't setted "w???._coord", the "normal"-coordinate
is used for both modes.
* added a new constructor for GuiImageData
currebtly the constructor is unused, i will use later
