Scaled sample 10-Masks slow on android

[codeservice]

I tried sample “10-Masks” on android
https://github.com/haxenme/nme/tree/master/samples/10-Masks

It works well unless I add stage.scaleX = stage.scaleY = 2
Scaled version extremely slow on android. I don’t see problem with this on windows. Maybe scaled version creates to big textures for android to process. Performance proportional to scale. Issue looks similar to this #331
