any limitations for images loaded by CCTextureCache on windows?

platform: windows
version: 2.0.3

tried on some mobile devices, it crashed when the size of image for creating sprite was over 3000 by 2000. Now I’m just doing experiments on windows, and it never crashed even when the size of image comes to over 7000 by 5000. saw some posts on the web saying the limit size on windows is 4096 by 4096, which is obviously not correct.

anyone know about stuff on this? or any insights on CCSprite, CCTextureCache are welcomed.
