Comment 2 for bug 1615073

For me, adding a flag to the dvipngcmd tuple in plugins.equationeditor.py seems to work as a workaround:

-dvipngcmd = ('dvipng', '-q', '-bg', 'Transparent', '-T', 'tight', '-o')
+dvipngcmd = ('dvipng', '-q', '-D', '180', '-bg', 'Transparent', '-T', 'tight', '-o')

For general use, the `180` should probably be settable, but I am, for the moment, happy with my hardcoded value.
