+/** NOTES on threading:
+ * internal: thread race prevention is done via the 'docLock' mutex. the
+ *           mutex is needed only because we have the asyncronous thread; else
+ *           the operations are all within the 'gui' thread, scheduled by the
+ *           Qt scheduler and no mutex is needed.
+ * external: dangerous operations are all locked via mutex internally, and the
+ *           only needed external thing is the 'canGeneratePixmap' method
+ *           that tells if the generator is free (since we don't want an
+ *           internal queue to store PixmapRequests). A generatedPixmap call
+ *           without the 'ready' flag set, results in undefined behavior.
+ * So, as example, printing while generating a pixmap asyncronously is safe,
+ * it might only block the gui thread by 1) waiting for the mutex to unlock
+ * in async thread and 2) doing the 'heavy' print operation.
