Blitter doesn't draw lines of width > 1 correctly:

  1. Sometimes there are some pixels moved at the beginning or end of the line.
  2. The width of the line doesn't match the one passed as an argument.

GfxDrawLine(x_zero, y_zero, x_zero, y_max, _colour_gradient[COLOUR_BLUE][1], 4);
GfxDrawLine(x_max, y_zero, x_max, y_max, _colour_gradient[COLOUR_BLUE][1], 5);
See attached image:
lines
... where the left line should have a width of 5 and the right one a width of 4 pixels (and they have a width of 4 and 3 respectively).

I can't reproduce the thickness issue.

GfxDrawLine(x_zero +  0, y_zero, x_zero +  0, y_max, 1, 1);
GfxDrawLine(x_zero +  5, y_zero, x_zero +  5, y_max, 1, 2);
GfxDrawLine(x_zero + 10, y_zero, x_zero + 10, y_max, 1, 3);
GfxDrawLine(x_zero + 15, y_zero, x_zero + 15, y_max, 1, 4);
GfxDrawLine(x_zero + 22, y_zero, x_zero + 22, y_max, 1, 5);
GfxDrawLine(x_zero + 30, y_zero, x_zero + 30, y_max, 1, 6);
