swaybar: fix rendering of border and background

Browse Source 
This fixes the rendering of borders and backgrounds for blocks. This
also makes the following changes:
* both borders and padding are scaled with the output
* both lines and rectangles are rendered without an antialiasing to
avoid bleeding outside the desired area
