Hi,
Here are three patches to add skia, a graphics library and add support
for it in icecat. It is not made the default graphics engine, so to
enable it, you need to go in about:config and change
`gfx.content.azure.backends' and `gfx.canvas.azure.backends' to `skia'
instead of cairo. Doing this seems to solve the random crashes.
