//! The OpMarkupMouse class inserts a 2D rectange into a markup layer. If a markup layer is already active then the operator will use that layer otherwise the operator will create a new, unamed layer.

/*!

HOpMarkupMouse implements three mouse event methods defined on the base class and maps the event information
|
||
|
|
to operator routines. This operation consists of the following steps:
|
||
|
|
<ol>
|
||
|
|
<li>Left Button Down: register corner of rectangle
|
||
|
|
<li>Left Button Down and Drag: create an appropriately sized rectangle in the contruction layer
|
||
|
|
<li>Left Button Up: depending on existence of an active markup layer it either opens the existing or creates a new markup layer and inserts appropraitely sized rectangle into it
|
||
|
|
</ol>
|
||
|
|
