This is similar to bug 104403, but for SVG table instead (https://www.microsoft.com/typography/otspec/svg.htm). This might be a trickier as instead of rendering layered glyphs with different colors we will need to render SVG graphics. We already have decent SVG support, but I’m not sure how usable is it from a low level as text rendering in VCL.
Steps to Reproduce:
Using the bundled Emoji One font.
Emoji glyphs are monochrome.
They should be colored.

HarfBuzz merged a pull request recently to add support for SVG table, but require additional support to work with gz extractor.
Everyone can focusing on the following bug report at GitHub, this will discussing which API will be available for getting SVG glyphs.
