/**
* @file u_log.h
* @brief Context logging facilities
*
* Provides a means of logging context events (draw calls, command streams, ...)
* into files.
*
* Log entries start their life cycle as "chunks". Chunks can be plain text
* written by \ref u_log_printf or custom internal representations added by
* \ref u_log_chunk that are only converted to text on-demand (e.g. for higher
* performance pipelined hang-debugging).
*
* Chunks are accumulated into "pages". The manager of the log can periodically
* take out the current page using \ref u_log_new_page and dump it to a file.
