}Expand description
Contains the work (in the form of instance arrays) needed to fill a color color (RGBA8) or alpha output surface.
In graphics parlance, a “render target” usually means “a surface (texture or
framebuffer) bound to the output of a shader”. This struct has a slightly
different meaning, in that it represents the operations on that surface
before it’s actually bound and rendered. So a RenderTarget is built by
the RenderBackend by inserting tasks, and then shipped over to the
Renderer where a device surface is resolved and the tasks are transformed
into draw commands on that surface.
