TITLE: Paint Operation

The Paint operation allows you to interactively paint the colors of your
geometry.

As you move the mouse over the geometry, you will see a circular brush follow
the surface to show where you would paint.  The size of this brush and its
orientation will show you which points will be affected by a paint operation.

Like all the brush tools, you have two different brushes: your Foreground brush
and your Background brush.  You paint with your foreground brush using the LMB
and the background with the MMB.  The color painted is controlled by the "FG"
and "BG" parameters respectively.  

Each of the brushes also can have its own independent operation.  To select the
operation for each brush, Ctrl-RMB to bring up the operation menu.  The options
are:

- Paint: This paints your new color onto the geometry.
- Eye Dropper: This takes the color of the point nearest the center
  of your brush and sets it to that brush's painting color.
- Smooth: This smoothly blends the colors of nearby points under the
  brush.
- Erase Changes: Thus is a local undo - it restores the colors under
  your brush to the pre-paint values.

The other main parameters are:

- Radius: The size of the brush.
- Opacity: How strong the brush is.  A fully opaque brush replaces the
  original colour, while a less opaque brush blends it.

The other Ctrl-RMB Menu options are:

- Circle/Square/Bitmap Brush: The shape of the brush.  The bitmap is
  set in the operation parameters dialog.
- Orient Brush To Surface: When disabled, the brush is always oriented
  the same way.  This is useful when painting crinkly geometry.
- Accumulate to Stencil: This advanced option is described in more
  detail in the manual.
