Remarks

Creates an instance of a hardware-accelerated renderer. This is used to render a scene built from RenderNodes to an output HardwareBuffer. There can be as many HardwareBufferRenderer instances as desired.

<h3>Resources & lifecycle</h3>

All HardwareBufferRenderer and HardwareRenderer instances share a common render thread. Therefore HardwareBufferRenderer will share common resources and GPU utilization with hardware accelerated rendering initiated by the UI thread of an application. The render thread contains the GPU context & resources necessary to do GPU-accelerated rendering. As such, the first HardwareBufferRenderer created comes with the cost of also creating the associated GPU contexts, however each incremental HardwareBufferRenderer thereafter is fairly cheap. The expected usage is to have a HardwareBufferRenderer instance for every active HardwareBuffer.

This is useful in situations where a scene built with RenderNodes can be consumed directly by the system compositor through SurfaceControl.Transaction#setBuffer(SurfaceControl, HardwareBuffer).

HardwareBufferRenderer will never clear contents before each draw invocation so previous contents in the HardwareBuffer target will be preserved across renders.
