Details:

Turning on the minor grid on a brand new axes object does not always display
the minor grid.  refresh() and drawnow() do not cause the grid to be drawn. 
However, if the plot window is resized using a mouse the re-paint event causes
the grid to be displayed.

This isn't of high importance.  It seems to work, for example, as long as
there is a child object of the axes such as a line object or surface object. 
This is probably a clue.  Also, anything that updates the axis limits also
causes the correct behavior.

Failing example:


close all
graphics_toolkit qt
gca
grid minor


Working example:


close all
gca
xlim ([0 2]);
ylim ([0 2]);
grid minor
