Adjust offset for non-AA line drawing
bug:8114304
The original .375 was chosen to make GL_LINES align with Skia drawing.
The new value of .065 is chosen to be as small as possible to make
triangle-based lines align with Skia, while keeping lines drawn on
integer coordinates unambiguous as to which column/row they draw on.
Also adds more lines in CanvasCompare test to highlight the difference
