[cairo] Using the span renderer to push spans to an FPGA?

[Leon Woestenberg]

Hello,

my current cairo backend is the image backend, which copies images
line-by-line to an FPGA for display.

As we have control over the FPGA, I wondered if the span renderer be
exploited to send spans to the FPGA, instead of the raw image data?

Regards,
