The earlier design speculated that embedders could affect the same transformations on the layers post engine compositor presentation but before final composition. However, the linked issue points out that this design is not suitable for use with hardware overlay planes. When rendering to the same, to affect the transformation before composition, embedders would have to render to an off-screen render target and then apply the transformation before presentation. This patch negates the need for that off-screen render pass. To be clear, the previous architecture is still fully viable. Embedders still have full control over layer transformations before composition. This is an optimization for the hardware overlay planes use-case. Fixes b/139758641
