Description

Examples and wrench main use case is assisting developers, which built WR locally in the first place. I suggest us having these binary to use local shaders by default, so that we can iterate quickly without putting the command line every time. Perhaps, even have a compile feature to include shaders in the build that is only used by Servo/Gecko? We could write the shader path by the build.rs somewhere, then read in the examples/wrench.

Contributor guide

Research direction
Investigate how shader paths are currently configured in examples and wrench, and how build.rs can write the shader path at compile time. Examine the existing command line options for shader paths and determine how to make local shaders default while preserving the ability to override.
