Pixeldeviceratio on Postprocessing examples

[throni3git]

Description of the problem

While in chrome using the possibility to emulate mobile devices with pixelDeviceRatio != 1 everything works, i'm getting coarse image quality for the postprocessing examples like

http://threejs.org/examples/#webgl_postprocessing_msaa_unbiased

I played with setPixelRatio and stuff, but none helped to get an appropriate rendering. Since a project of mine is heavily relying on these antialiasing processes, i'd like to figure out why this is rendering strange...

WebGLRenderTarget doesn't support pixelRatio.

There is been some talks about implementing that recently... 7e47e41
