What is the transparent color on color and monochrome phones?
In BREW 1.x, magenta is the transparent color for color devices and white is the transparent color on monochrome and 4-level gray devices. In BREW 2.0 onwards, the transparency color is changeable via IBITMAP_SetTransparencyColor. CONVERTBMP initializes the transparency color to be compatible with older versions of BREW (i.e. magenta and white). However there is no fixed transparency color for bitmaps obtained through other means.
