* Make SpriteBatchSceneObject shaders static, so we don't create them per instance * Avoid per frame shader/material creation in PostProcessing * Avoid per frame shader/material creation in HudPainter * Move a few more compute shaders into static members * Reduce allocations in NormalizeFilename * Reduce string allocations in Material.FromShader
