In the PDF file from the issue below, the fill alpha (`CA`) is set before drawing the circles using the `setGState` operator. Doing so causes the global alpha to be set on the canvas' context for the canvas back-end, but this was not handled in the SVG back-end. This patch fixes that by taking the fill opacity into account when drawing shading patterns in the same way as done elsewhere so it is only included if the value is non-default. Fixes mozilla#11812.

I attached the svg as txt because of the github upload restrictions.

Configuration:
Web browser and its version: Latest Chrome (80.0.3987.149)
PDF.js version: pdfjs-dist (2.4.456)
Steps to reproduce the problem:
Use the PDF above in the SVG renderer and you will see that image in the middle has two cirlces. the right circle should have 3 circles around them that each has less opacity. In the SVG renderer these circles are rendered with full opacity.
