// .NAME vtkBooleanTexture - generate 2D texture map based on combinations of inside, outside, and on region boundary

// .SECTION Description
// 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).
