Blur for PlayCanvas UI

@queriel

Hi - i found your blur.js script and was wondering, if you where able to fix the error message i still receive and you mentioned.

“Shader [Shader Id 4 FirstBlurShader] requires texture sampler [uSceneColorMap] which has not been set, while rendering [Pass:RenderPass-drawQuadWithShader-Blur: Horizontal | drawQuadWithShader | QuadRender]”

Would be awesome, so i could use it for a project. :slight_smile:
