Add a high-level function to retrieve color primaries. Wayland compositors will be interested in this. A high-level function may later be extended to support stand-alone DisplayID and other sources. The high-level data is derived from low-level API calls in di_info_parse_edid(). As we stash the results in struct di_info to avoid requiring the callers to explicitly free the high-level structures, this allows keeping struct di_info deeply const in high-level API implementation. We also avoid some dynamic allocations. https://github.com/linuxhw/EDID.git database contains 20399 samples for which edid-decode complains: Basic Display Parameters & Features: sRGB is signaled, but the chromaticities do not match. Therefore I assume that the sRGB flag is more correct when set. Signed-off-by: Pekka Paalanen <pekka.paalanen@collabora.com>
