\func{bool}{Union}{\param{const wxBitmap\&}{ bmp}}
Finds the union of this region and the the non-transparent pixels of a
bitmap. Bitmap's mask is used to determine transparency. If the bitmap doesn't
have a mask, solid rectangle of bitmap's dimensions is used.

Finds the union of this region and the the non-transparent pixels of a
bitmap. If the bitmap has a mask then it will be used, otherwise the
colour to be treated as transparent may be specified, along with an
bitmap. Colour to be treated as transparent is specified in the
\arg{transColour} argument, along with an
optional colour tolerance value.
