fluid.backend.headless

A headless backend. This backend does not actually render anything. This allows apps reliant on Fluid to run outside of graphical environments, provided an alternative method of access exist.

This backend is used internally in Fluid for performing tests. For this reason, this module may be configured to capture the output in a way that can be analyzed or compared againt later. This functionality is disabled by default due to significant overhead — use version Fluid_HeadlessOutput to turn it on.

If elemi is added as a dependency and Fluid_HeadlessOutput is set, the backend will also expose its experimental SVG export functionality through saveSVG. It is only intended for testing; note it will export text as embedded raster images rather than proper vector text.
