So. A while ago, while trying to prevent hogs blowtorching getting turned around, unc0rr altered the old range of blowtorch from 1/8th of 180° up or down, to a 4° gain in upwards and a -4° loss in downwards. He also made it so that starting tunnels could fail to erase sufficient terrain, trapping hogs. Here are a couple of workarounds to more closely approximate old behaviour (do some initial erasure, adjust min/max angles)

* This is a development version of <ft2build.h> that is used
* to build the library in debug mode. Its only difference with
* the reference is that it forces the use of the local `ftoption.h'
* which contains different settings for all configuration macros.
*
* To use it, you must define the environment variable FT2_BUILD_INCLUDE
* to point to the directory containing these two files (`ft2build.h' and
* `ftoption.h'), then invoke Jam as usual.
