[Interest] qml performance with Qt5.2

[Nancy Zou]

Dear Gunnar & other friends:

About atlas texture:
I print the atlas size in my system, QSG: texture atlas dimensions: 1024 x 1024
I use qml image item to load  a jpeg image with size of 640*640,  but I find it isn't the atlas texture. 

If  a smaller image like 200*200, it can be  the atlas texture. Why  the size 640*640 can't be  atlas?

I try to set SG_ATLAS_WIDTH=800, QSG_ATLAS_HEIGHT=800.  It's  not help.

Thank you for all your helps.

Best Regards
Nancy
