Add a new graphics protocol key, N=1, to request that transmitted image/frame data is kept only in memory and not written to the graphics disk cache file. This is useful for transient high-frequency updates such as video-like streams, where the latest frame is the only useful data and persisting each frame to the disk cache causes unnecessary write traffic. The implementation keeps the existing graphics cache abstraction intact: memory-only entries can still be read back by animation, composition, and frame coalescing paths. Only persistence to the disk cache file is skipped. The default behavior is unchanged when N is omitted or set to zero.
Scripts to generate code for various things like keys, mouse cursors, unicode data etc. Some of these generate code that is checked into version control. Some generate ephemeral code used during builds. Ephemeral code is in files with a _generated.[h|go|c] extension.
