Implement Bitmap 'blur' I was a bit confused at first because I thought Enterbrain had actually implemented a full Gaussian blur, but nope, just dumb averaging. 2013-10-01 18:10:43 +02:00

Shader: Refine preprocessing on GLES platform Don't globally set float precision to mediump, only fragment shaders need that and defining it for vertex shaders causes tilemap cracks. Also manually define low precision for variables that hold color / alpha values. 2014-12-23 18:33:33 +01:00			`lowp vec4 frag = vec4(0, 0, 0, 0);`
