Subject[PATCH 30/37] perf scripts python: exported-sql-viewer.py: Add ability to shrink / enlarge font
Date
From: Adrian Hunter <adrian.hunter@intel.com>

Shrinking the font allows more information to display.

Committer testing:

Works, tested with the convenient Control+Shift+'+' and Control+'-' as
well with the more cumbersome top menu "Edit" + "Enlarge/Shrink font"
options.
