At a high level, the first three steps of making a GrGLInterface (a generic way to
interact with a GL-like GPU) are:
Assemble: Copy a set of function pointers into the struct
Validate: Make sure the function pointers advertised actually exist.
Capabilities: Compute what fast/slow paths are enabled based on the functions
in the struct (GrGLCaps, for short)
Autogeneration
The first two steps have been automated with a table-based generation script located
in this folder. The table is in JSON5 format (like JSON, but with comments). O
Once edited, the Assemble/Validate code can be re-generated by running
make generate in this folder.
