alpha. (We verify its accuracy with a unit test.)

Fix a double scaling issue in Y'CbCr conversion.

We multiplied by 224/219 once too many, causing some small accuracy issues.
Furthermore, we also did this for full-range Y'CbCr, which obviously is wrong.
The issue was so small that the unit tests kept on passing (its investigation
was prompted by a test that failed on AMD cards, which is a separate issue).

these in another order than they are specified in the shader source,
