X_MULTMATRIX
X_MULTMATRIX mat[]
This command is the equivalent of the OpenGL command "glMultMatrix".
With this command you can multiply a 4x4 matrix with the current matrix (i.e. the matrix that describes the current rotation and zoom settings that will apply to any object drawn). The matrix mat[] must be DIMed [16] and have this structure:
| a0  a4  a8 a12 |
| a1  a5  a9 a13 |
| a2  a6 a10 a14 |
| a3  a7 a11 a15 |
