   Record by record transparency has been added to plot at #626, and also plot3d at #471, so what's left is just adding it to text?

   On a side note, we might want to add a test for grdimage with transparency. I'm getting this error on PyGMT v0.2.1, GMT 6.2.0_92c5676_2020.11.10 with ghostscript 9.53.3:

   fig = pygmt.Figure()
   fig.grdimage(grid="@earth_relief_01d", transparency=70)
   fig.show()

   GMTCLibError: Module 'psconvert' failed with status code 79:

   Will submit a proper bug report once I can isolate the issue.

   Yes, I think I already have a local branch for the text transparency. Will check if it works as expected and submit it later.

   I can't reproduce your issue, using PyGMT v0.2.2.dev14+g1547ad41 + GMT 6.2.0_74efdca_2020.12.06 + Ghostscript 9.53.3 on macOS.

   Great! No rush though, I was just searching for transparency examples and saw this issue was still open

   Yeah, I might need to update my GMT dev version, can't reproduce this on try-gmt either :/ Maybe GenericMappingTools/gmt#4464 fixed this.
