run ./bin/ext_framebuffer_multisample-accuracy 2 stencil_resolve -fbo -auto
output:
Pixels that should be unlit
count = 126470
Perfect output
Pixels that should be totally lit
count = 131408
RMS error = 0.708010
Pixels that should be partially lit
count = 4266
RMS error = 0.598696
The error threshold for this test is 0.400000
PIGLIT: {'result': 'fail' }
Reproduce steps:
----------------------------
1. xinit
2. ./bin/ext_framebuffer_multisample-accuracy 2 stencil_resolve -fbo -auto</pre>
