16bit DOS 3D cube in VGA mode 13h

Why? just for fun :) I've installed MSDOS 6.22 and windows 3.1 to an old pentium 166 mmx. Then I've installed every compiler I've ever used: Turbo C, Turbo Pascal 7, Borland C++ 3.1, OpenWatcom, nasm, etc. So I decided I should write a bit of 16bit DOS graphics code for old time's sake in VGA mode 13h (320x200 8bpp). For this trip to the past I hacked together a really quick and dirty (and incomplete: no clipping or lighting) software renderer with an OpenGL-like API.
