1634452 - Allow SWGL vertex shaders and fragment shaders to share data

Status: RESOLVED FIXED

(Core :: Graphics: WebRender, enhancement, P3)

Description

[Lee Salzman [:lsalzman]]

Currently SWGL stores separate copies of flat interpolants, uniforms, and samplers for vertex shaders and fragment shaders. We can just make the fragment shader inherit from the vertex shader, which allows us to only have to store one copy of these, and also obviates the need to store them out and read them back to transition from vertex shader to fragment shader per-primitive. This will help offset the performance cost of perspective checking in bug 1634447.
