Performance of Unmanaged_BufferredImage_draw_NearestNeighbor j2dbench image rendering test dropped between the lanai build of 5 oct 2020 and build of 30Nov 2020.

The following test results are average of all the test of Unmanaged_BufferredImage_draw_NearestNeighbor test

est performance for metal pipeline
Before : 525375.3592 pixels/msec
After : 244651.6941 pixels/msec

Test performance for opengl pipeline
Before : 112373.5543 pixels/msec
After :101211.3426 pixels/msec

Test Unmanaged_BufferredImage_draw_NearestNeighbor is attached

The performance of metal pipeline is still better than opengl.
