[OE-core] [PATCH 4/4] scripts/pybootchart/draw: Fix some bounding problems

[Richard Purdie]

The chart size extents were being incorrectly reported, not accounting for the
width of the legend. Set a minimum width to account for that (its fixed size).

Also stop printing the chart background off the bottom of the chart extents.
