Details:

Sample code to reproduce:


set (groot, 'DefaultAxesTitleFontSizeMultiplier', 2);
set (groot, 'DefaultAxesFontSize', 10);
set (groot, 'DefaultTextFontSize', 12);
hax = gca;
ht = get (hax, 'Title');
get (ht, 'FontSize')


The returned font size should be 20 (2 x 10) but instead is 12.  Matlab gets
this right.  It also affects the "LabelFontSizeMultiplier" property.

The "Title" object is of type "text", but it should be initialized with the
correct "FontSize" property.  The code in graphics.cc for the function
axes::properties::init does the right thing.  There may be a race condition
involved or an order of execution issue for the setting of properties.
