| * Description: Header file for the MegaGraph Graphics Library. You can |
| * defined one of the following to specify which MGL API you |
| * wish to use. |
| * |
| * MGL_LITE - Compile for the MGL/Lite API |
| * MGL_PRO - Compile for the MGL/Pro API |
| * MGL_FIX3D - Compile for the MGL/3D API (fixed point) |
| * MGL_FLT3D - Compile for the MGL/3D API (floating point) |
| * |
| * If you do not define any of these, MGL_FIX3D will be defined |
| * automatically for compatibility with older versions of the |
| * MGL. |
