axial transparency gradient on solid color

Open attached document and save it to pptx format.
Open the saved file in LibreOffice or PowerPoint.
Notice, that the gradient is no longer axial, but is linear with two stops.
It should be a linear gradient with three stops in pptx, same as it would be with a color gradient.

This is no regression. It is already wrong before MCGR, but should be fixed by MCGR.
