**GFX_BEGIN

Starts the processing of primitives.
31..2	?
1..0	Type (00: Triangles, 01: Quads, 10: Triangle Strip, 11: Quad Strip)


**GFX_END

Stops the processing of primitives / finalizes them.

Just like OpenGL, you should only issue vertex commands in between a begin / end pair.

libnds function calls associated with these registers:

    * glBegin
    * glEnd 

**MATRIX_TRANSLATE

Three writes multiples the current matrix with a translate matrix of the form:
1.0	0.0	0.0	write1
0.0	1.0	0.0	write2
0.0	0.0	1.0	write3
0.0	0.0	0.0	1.0

libnds function calls associated with these registers:

    * glTranslatev
    * glTranslate3f32
    * glTranslatef32
    * glTranslatef 

**MATRIX_SCALE

Three writes multiples the current matrix with a scale matrix of the form:
write1	0.0	0.0	0.0
0.0	write2	0.0	0.0
0.0	0.0	write3	0.0
0.0	0.0	0.0	1.0

libnds function calls associated with these registers:

    * glScalev
    * glScalef32
    * glScalef 

**MATRIX_MULT3x3

After 9 writes, the current matrix is multipled by a 3x3 matrix formed from the writes.

**MATRIX_MULT4x3

After 12 writes, the current matrix is multipled by a 4x3 matrix formed from the writes.

**MATRIX_MULT4x4

After 16 writes, the current matrix is multipled by a 3x3 matrix formed from the writes.

libnds function calls associated with these registers:

    * glMultMatrix3x3
    * glMultMatrix4x3
    * glMultMatrix4x4 

**MATRIX_LOAD4x4

Write port to the 4x4 matrix hardware (f32 format).


**MATRIX_LOAD4x3

Write port to the 4x4 matrix hardware (f32 format). After 12 writes, the last 4 elements of the matrix are set to 0.0 0.0 0.0 1.0.

libnds function calls associated with these registers:

-glLoadMatrix4x3
-glLoadMatrix4x4
-Various other routines use them behind the scenes. 

libnds fixed point / floating point / integer conversion routines:

-intof32 (integer -> f32)
-floatof32 (float -> f32)
-inttot16 (integer -> t16)
-floattot16 (float -> t16)
-inttov16 (integer -> v16)
-floattov16 (float -> v16)
-inttov10 (integer -> v10)
-floattov10 (float -> v10)
