For unknown reasons, sometimes glTexSubImage2D acts as if
GL_UNPACK_ALIGNMENT = 2 or 4, instead of 1. This causes the odd-sized
array uploaded for the LOS texture to be interpreted incorrectly, and
the LOS texture gets rendered very incorrectly.
Pad the array to a multiple of 4 in all cases, so that
GL_UNPACK_ALIGNMENT shouldn't affect it.
Hopefully fixes#2594.
This was SVN commit r15216.
Replace New dialog box with separate tools for resizing maps and
replacing terrain textures, to provide more power and to simplify the
problem of initialising map settings.
Fix engine to cope with dynamic map resizing.
Add JSON support to AtObj, to let C++ interact with JSON more easily.
This was SVN commit r9566.
Fix particles in Actor Viewer.
Expand terrain in Actor Viewer.
Change background to black so it blends with the LOS texture more
nicely.
This was SVN commit r9172.
Change lighting model for new maps to allow better overbrightness.
Cache player colours instead of loading from scripts every time the
renderer wants them.
This was SVN commit r9123.
