New commits: commit 51ba2df1cb29d4343f92174da6dc8f36ba9152eb Author: Zolnai Tamás <[email protected]> Date: Tue Jul 15 23:37:10 2014 +0200 fdo#81182: Resizing glTF window affects camera position Camera moves by click and drag, with checking the last mouse position we can make sure click was done inside the window before drag. Resizing can trigger drag event, but not click event.

Calling releasFbo removes size dependent objects and triggers creating the new ones with the new size.
