The 1.41o daily build adds a Toolbar.setBrushSize() method that macros
can call to set the size of the brush tool.
a=call("ij.gui.Toolbar.getBrushSize");
b=call("ij.gui.Toolbar.setBrushSize",2*a);
a=call("ij.gui.Toolbar.getBrushSize");
print(a);
Note that Toolbar.getBrushSize() returns 0 if the brush tool is not
enabled and Toolbar.setBrushSize() is not allowed to set the size to
less than 5.
