Additions

• Add Filter support to Layer.
• Allow RenderTexture to automatically re-render.
  • DynamicTexture#preserve() allows you to keep the command buffer for reuse after rendering.
  • DynamicTexture#callback() allows you to run callbacks during command buffer execution.
  • RenderTexture.setTextureMode() allows you to set the RenderTexture to automatically re-render during the render loop.

Fixes and Eliminations

• Fix roundPixels handling in many places, mostly by removing it from irrelevant situations.
  • Remove TransformMatrix#setQuad parameter roundPixels, as it is no longer used.
• Filters are correctly destroyed along with their owners, unless ignoreDestroy is enabled. This supports multi-owner Filter controllers.
• WebGLRenderer destroys itself properly.
• Remove unnecessary transform related to camera scroll.
• Remove references to Mesh.
• Fix UV coordinates in Shader.
• Shader#setTextures() now replaces the texture array, rather than adding to it.
• Fix SpriteGPULayer#getMember(), which previously multiplied the index by 4.
• Fix flipX/flipY in Filter#focusFilters.
• Fix BatchHandlerQuad#run() parameter tintFill, which was set as a Number but should be used as a Boolean.
• Eliminate rounding in Camera#preRender().
