Max size of textures in cocos2d-x depends on each platform

In theory, cocos2d-x could show textures in any size, but actually the maxsize of the textures is restricted by the hardware and the system.
Here I provide a texture-size restriction table on different platforms' emulators.

platform maxsize in pixels
win32 2048*2048
android 4096*4096
iPhone3 1024*1024
iPhone3GS 2048*2048
iPhone4 2048*2048

On the real machines, they aslo have different restrictions, here are some test results: G3 1024*1024, iPhone4 2048*2048.

So, for the developers, if you want to cross platforms and run your games smoothly, you should keep your texture size less than 1024*1024, that is the lowest retriction for most machines.
