Linear filtering + Shader dusting

[Firepal]

MirrorMaterial:

• no longer a binary file
• ViewportTexture now looks smooth and not blocky. Linear filtering is cheap

MirrorShader:

• MeshInstancedFlipped removed, superseded by siÃmple shader math
• Linear2srgb separated and disabled, replaced with the (cheaper?) Keep 3D Linear in Viewport

forgot to version bump in plugin.cfg, welp

Very good changes, I really like it.

Np. I will try and do more when I'm off holiday :)

One thing missing is a default distortion texture.

The best would be to export the distortion texture to the top level script to let the user pick one as they see fit. Do you know how that could be done?

Easy. We can make an exported Texture variable, and add a setter function to it that sets the given texture (or if null, the default stored as a .tres) on the shader using ShaderMaterial.set_shader_param(name,value).

Instead of only fixing the missing texture, we could implement that and solve two in one!

Damn it. I even searched for it but now that you mention I immediately find this type of export variable.
