      Description

      Commit 8c745d808527684836d04da9014ee33c7cf8b6f1 contains multiple optimizations for QQuickOpenGLShaderEffect:

      • Don't use a signal mapper, but handle the mapping using a custom slot object and a lambda to do the dispatching ourselves.
      • Don't do meta-calls by property name, but by index.
      • Cache the meta-object.
      • Resolve the property indices by using the QML property cache.

      These need to be ported to QQuickGenericShaderEffect.
