Test on all target platform combinations to see if we can make VendorNamesExceptedFromSwapGlFinishRequirement go away. #1164
Description
The use of Gl.Finish should be absolutely non-essential to any well implemented driver with correct client programming as it can cause rendering to slow down by 30% plus where used inappropriately. If we can remove the use of Gl.Finish on all target platform combinations without rendering errors, we should absolutely remove this and all the implicated usages of Gl.Finish.
