Use "pragma max_page_count" to define max allowed file size in combination with "pragma page_size" based on a new setting "max navmeshdb file size". * Stop navmeshtool on the first db error. * Disable writes to db in the engine on first "database or disk is full" SQLite3 error. There is no special error code for this error. * Change default "write to navmeshdb" to true. * Use time intervals for transaction duration instead of number of changes.
