PyDMDrawingPolyline lines rendering a bit blurry/fuzzy #1089

for example: in this screenshot I have (from left to right): a PyDM polyline with penWidth=1, then another polyline width=3, and then a PyQT line also width=3. if we zoom in, we can see the polyline section is blurrier than the PyQT line with same width can make a pydm issue with this and take a closer look Screenshot_2024-07-08_10-46-29

Original report (https://slac.slack.com/archives/C6B8GRCPQ/p1720463903713689?thread_ts=1719959015.207139&cid=C6B8GRCPQ):

I’m trying to pydm-ify some edm and the lines are fuzzier! In edm lineWidth=1 (left) and on the pydm it’s 0.6 (right). If I thicken it, it gets fuzzier. Any suggestions? This is a PyDMDrawingPolyline widget. Both lines are black (0,0,0)
