Detailed Description

a thread to fetch an image in the background

the image can be polled by the field 'pixels' which stays null until image is successfully received and decoded. the user then has to reset 'pixels' to null to notify the ImageFetcher that ressouces can be freed!

we use no listener pattern as he GL part relies in one thread and we have to fill texture there.
