This workaround fixes a long-living issue with exporting the marker to PDF.
Due to peculiarities of PDF rendering on some zoom levels there might appear little gaps between marker's "pixels", that look like this:
I guess, these artifacts might apper on a printed version of marker, which is definitely not good.
SVG's attribute shape-rendering set to crispEdges doesn't save the situation. Changing of any related SVG parameter's doesn't help as well.
This patch implements a workaround for this. For each white pixel of a marker, if there is a white pixel on the right, the width of the pixel is increased to 1.5 to overlap potential gap.
If there is a white pixel under it, another white rect is added with height 1.5 to overlap the gap as well.
Thus, the rendered PDF is guaranteed to not have such artifacts:
