/**
 * @class   vtkBooleanTexture
 * @brief   generate 2D texture map based on combinations of inside, outside, and on region boundary
 *
 *
 * vtkBooleanTexture is a filter to generate a 2D texture map based on
 * combinations of inside, outside, and on region boundary. The "region" is
 * implicitly represented via 2D texture coordinates. These texture
 * coordinates are normally generated using a filter like
 * vtkImplicitTextureCoords, which generates the texture coordinates for
 * any implicit function.
 *
 * vtkBooleanTexture generates the map according to the s-t texture
 * coordinates plus the notion of being in, on, or outside of a
 * region. An in region is when the texture coordinate is between
 * (0,0.5-thickness/2).  An out region is where the texture coordinate
 * is (0.5+thickness/2). An on region is between
 * (0.5-thickness/2,0.5+thickness/2). The combination in, on, and out
 * for each of the s-t texture coordinates results in 16 possible
 * combinations (see text). For each combination, a different value of
 * intensity and transparency can be assigned. To assign maximum intensity
 * and/or opacity use the value 255. A minimum value of 0 results in
 * a black region (for intensity) and a fully transparent region (for
 * transparency).
