- Implement AI land marks which only used to tracks visited areas on the map for now. Significantly reduces wasting of cpu time by AI checking same place several times (10x or even more in rare cases)
- More branching in walk algorythm which allows for better coverage of reachable places. Sometimes makes AI perform ridiculous jumping just to make a tiny step.
- Small fixes/adjustments

* @function:

*
* @description:
* Validate various OpenType tables to assure that all offsets and
* indices are valid. The idea is that a higher-level library which
* actually does the text layout can access those tables without
* error checking (which can be quite time consuming).
*
* @input:
* face ::
* A handle to the input face.
*
* validation_flags ::
* A bit field which specifies the tables to be validated. See
* @FT_VALIDATE_OTXXX for possible values.
*
* @output:
* BASE_table ::
* A pointer to the BASE table.
*
* GDEF_table ::
* A pointer to the GDEF table.
*
* GPOS_table ::
* A pointer to the GPOS table.
*
* GSUB_table ::
* A pointer to the GSUB table.
*
* JSTF_table ::
* A pointer to the JSTF table.
*
* @return:
* FreeType error code. 0~means success.
*
* @note:
* This function only works with OpenType fonts, returning an error
* otherwise.
*
* After use, the application should deallocate the five tables with
* @FT_OpenType_Free. A NULL value indicates that the table either
* doesn't exist in the font, or the application hasn't asked for
