1D Line Draw with Broken Pattern 0xAAAA
2D Line Draw with Broken Pattern 0xEBBB
Figure 45-4. Line Draw From (0,0) to (1,0) and Update XY Four Times
The first pixel drawn is based on the least significant bit of the pattern register. In this example
the first pixel is not drawn. After rendering each pixel, the pattern register is rotated to the right
by one bit.
Figure 45-5. 1D Line Draw From (0,0) to (5,0) with Broken Pattern 0xAAAA
In 2D line drawing, the bit pattern does not rotate. Each pixel rendered is based on the last two
bits of its X and Y addresses as shown below.
