NSVG_PAINT_RADIAL_GRADIENT about cairowidget HOT 2 CLOSED

So, I found the issue.
First we need to implement the pull request memononen/nanosvg#164 for nanosvg, then we need to change line 126 in caironanosvg.cpp to

pat = cairo_pattern_create_radial(g.fx * -r, g.fy * -r, 0.,
              t[4], t[5], r);

that makes all radial gradients shine!

I long suspected there might be issues with radial gradients. Now that you have spotted the error, I'll put your fix into CairoWidget and qtnanosvg, thank you. Previously, I only made a "best-effort" as regards radial gradients, as seemingly, there are problems within nanosvg itself and I use it only for generating icons, which means the .svgs I render are rather simple and usually contain no radial gradients. Even with radial gradients supported, nanosvg is rather incomplete, there is no filter support, for example. I am hoping for some other .svg library to emerge, but until then nanosvg will have to do.
