Emmanuele Bassi	23084b9768	docs: Effects fixes for the API reference	2010-06-03 14:34:41 +01:00
Emmanuele Bassi	0e9a1dee6d	shader-effect: Simplify setting the shader source ... Sub-classes of ShaderEffect currently have to get the handle for the Cogl shader and call cogl_shader_source(); this makes it awkward to implement a ShaderEffect, and it exposes handles and Cogl API that we might want to change in the future. We should provide a ClutterShaderEffect method that allows to (safely) set the shader source at the right time for sub-classes to use.	2010-06-03 14:10:55 +01:00
Emmanuele Bassi	5a5b21446c	effect: Add BlurEffect ... A simple, GLSL shader-based blur effect. The blur shader is taken straight from the test-shader.c interactive test case. It's a fairly clunky, inefficient and visually incorrect implementation of a box blur, but it's all we have right now until I figure out a way to do multi-pass shading with the current API.	2010-06-03 14:10:55 +01:00
