[v4] Intent Clarification: Filter vs Shader

Looking through the examples and issues, I see lots of demos for filters - but few for shaders.

What is the Pixi intended paradigm for when to use a filter vs a shader? For example, when is it recommended or appropriate to use Sprite.filters = [myFilter] vs Sprite.shader = myShader?

I don’t know what paradygm was used in the start.

How i see it:

Shader is for mass sprites/meshes. Shader calls are batched, streamed. 1000 elements with a shader are ok. Filter is applied to one big sprite/container to make it look cool. 1000 sprites with Filter will destroy your performance.

1. Filter must be applied to region of texture, and not full texture, (mapCoord,unmapCoord) is required if its not pixel-to-pixel shader.
2. Filter must use filterClamp, otherwise there’ll be problems
3. It may have two inputs - the “background” and “sprite” that it applies on it.
