Usage Notes:
Map file could be opened in Valve Hammer 3.4 editor (prefered bit windows only)
or passed to orignal's or ZLHT's compiler tools (use wine to run them on linux)
MAP format defines solids (brushes) as a set of intersecting planes.
Planes a defined by 3 points in space (could be different from face's vertices)
This is (very) unusual. This cannot reprents things such as :
* Concave meshes
* Non-planar faces
Existing tools that use this .map format probably don't cope with :
* ngons with n > 32
For now this script do :
* For each mesh in current scene
** Simplify it (remove doubles in vertices, fill holes, connect vertices to not have concave faces nor non planar faces)
** Recalc face normals to have them pointing to this outside of the mesh
* For each object in current scene that is type 'MESH'
** Take the mesh and local to world matrix
** Make a .map brush for each mesh's blender face (world coords, scaled by blender_to_map_scale_factor)
** Put AAATRIGGER texture stupidly
** Output it as part of worldspawn entity in .map
