ggsave: saving `geomImshow()` to SVG produces fuzzy picture

[alshan]

Try ggsave the last plot in image_101.ipynb to svg :

Saving to HTML is fine.

Same issue in Python LP.

In prev. LP v3.1.0 (py) saving imshow to SVG worked producing sharp images.

Test notebook:

%use lets-plot
%use lib-ext

LetsPlot.getInfo()

fun display(path: String): Any {
    if (path.endsWith("svg")) {
        val svg = Files.readString(Path.of(path))
        return HTML(svg)
    } else {
        val img = ImageIO.read(File(path))
        return Image(img)
    }
}

        )
    )
)

//%

val p = ggplot() + geomImshow(A2x3x4)
p.show()

//%

display(ggsave(p, "LPK-188.svg"))

//%

display(ggsave(p, "LPK-188.png"))
