render slide layers with VCL / drawinglayer primitives Instead of using slideshow module to render the slide layers, use the VCL / drawinglayer instead, which makes it possible to render transparency correctly and fast.

render master and slide content separately (drawinglayer render) This renders master and the main slide as 2 separate layers, which is useful because in a huge slideshow we can reuse the master slide and only render the rest of the slide, which should be more compact in size as the master slide is the one that usually contains the (complex) background.
