This PR removes dpi_scaleing of maximum width setting.

This seems incorrect because I expect maximum width to use absolute pixel value, otherwise meaning of maximum_width setting changes with DPI:

image
NOTE: Height difference is caused by font height, conky height can't be limited.

This fixes #1528.

This PR also fixes a regression introduced in #1841, where I incorrectly assumed templated base class function would be overriden by display outputs so DPI scaling was completely disabled.

Other changes

This PR also:

  • sets workspace dimensions from WL output_geometry because workspace is used for some calculations in conky.cc.
    • this requires more work for proper support as noted in comments, but it should make Wayland less broken.
  • adds conky xdg dir and script parent directory to Lua path so that scripts don't have to update it manually.

Testing

Set workspace dimensions from WL output_geometry

Adding $HOME/.config/conky and config parent directory to lua path before loading the script.

I believe (value > 0 ? 48 : -48) was rounding the result for int values before, so I replaced it with ceil and floor in new code. PIXELS_PER_INCH is 96.
