Const1 = 2 x dmin
This register is unchanged after the vector is completed.
This register holds the vector length, drawing octant, and the initial error value for the
Bresenham line algorithm. The initial value of the error term is held in bits 31:16 and
is computed by the host processor:
InitErr = 2 x dmin - dmax
Len = dmax + 1
where dmin = min (dx,dy), dmax = max(dx,dy)
The last pixel can be left undrawn by simply decrementing the Len parameter prior to
loading.
Note: Loading the high byte of this register starts the vector drawing engine.
A Len value of 0 is illegal and should be avoided.
This register is unchanged after the vector is completed, but you need to reload it to
start the next vector anyway.

Description
Initial error value for the Bresenham line algorithm
Bits 15:13 specify the drawing octant as follows:
Bit 15
1 = Y is major axis
0 = X is major axis
Bit 14
1 = negative X step
0 = positive X step
Bit 13
1 = negative Y step
0 = positive Y step
Length of the major axis in pixels
