Rhino WIP | Bug | Layout Transparency Printing Issues with OpenGL and D3D

Adding @stevebaer because you were the one who responded to my last layout problems in 2023! (for 8…)

On Windows 11, NVIDIA 4070TI…

In latest WIP, when attempting to print to a png with a transparent background you get either a rasterized checkerboard with OpenGL or no transparency and tile artifacts with D3D.

You can see the tiling artifacts even in the transparent RENDERED checkerboard pattern.
