Bug 95061 – [Tests] Make fast/canvas/canvas-scale-shadowBlur.html in conformance with spec.

• Component: Tools / Tests
• Status: UNCONFIRMED

[Dongseong Hwang]

This test failed on firefox because this test assumed the pixel apart from 2σ is #0000.
However, the pixel apart from 2σ is not #0000 mathematically. The exact value of
gaussian function f(2σ) is 0.1353. This means we should check
shouldBeTrue('d[0] == 255 && d[3] < 14'), but some platforms do not render
anything on the pixel apart from 2σ. i.e. skia.
So we need complex checking mechanism for d[0] and d[3] in order to be
harmonized with both the mathematical expectation and the practical expectation.

Yes, cr-linux bot failed.

However, I can not understand why cr-linux bot applied only new test file without the new expected file belonging to this patch. I think it maybe flaky nature of cr-linux.

I'll upload this patch again.

I had misunderstood the reason.

There are 4 platform specific expected files for relieving this problem.
cr-linux bot failed, because I did not update the expected file of cr-linux.
We does not need 4 platform specific expected files anymore, so I removed those.
