stuff. Overlay load function auto-detects FEAT-like images and creates
FEATImage instances instead of Image instances where necessary.

group in HistogramControlPanel.

HistogramListPanel (if it exists) via a slightly convoluted process
involving the 'HistogramPanel.selectedSeries' property.

subclasses manage their properties separately. New property on
HistogramPanel - selectedSeries - which will be used to link the
HistogramListPanel with the HistogramControlPanel without them
explicitly knowing about each other.

creating RGB array - this allows us to save as PDF/SVG/etc/etc.

its functionlaity is used, but it is not displayed. Log plots are now
done using matplotlib scale='log'. Ticks are now automatically generated
by matplotlib instead of being manually generated by me.

changes. More logging in HistogramPanel.

initial histogram calculation.

avoid having to perform the initial data range/histogram calculation

in end-bins of histogram. Tweaks to histogram data to make it look
better (i.e. plot ends finish at y=0.0). PlotPanel.drawDataSeries
accepts arbitrary **kwargs which are passed through to the plt.plot
function (and used by the HistogramPanel to draw histograms as step
plots).

enabling. Was caused by bug in the props bindable module.

due to the random creation of a VolumeOpts instance. To fix this, I
updated the Display class to accept an overlayType in the constructor,
and accordingly updated DC.getDisplay/getOpts methods. But display range
reset still occurring, so I need to do some bug finding.
Associated bugfix to ColourMapTexture border setting.

is done by subclasses. This is due to HistogramPanel.autoBin
complicatedness - the data series need to be refreshed before the plot
is refreshed.
