Don't know why only default_framebuffer_04 on Mac Nvidia still fail(bots told me
this failure). But all other tests against blitting out-of-bounds can pass on
Mac Intel/NVidia/AMD and on Linux Intel/AMD. 

And I can not reproduce this issue because I have no Mac Nvidia device at my
side. Maybe we can file a bug specific for Mac Nvidia for this only failure.
