 * MWPIXELVAL definition: changes based on target system

 *
 * For the Nano-X server, it is important to use the correct MWPF_* value
 * for the MWPIXEL_FORMAT macro in order to match the hardware,
 * while the Nano-X clients that includes this file can get away with
 * a default pixel format of 24-bit color as the client will either:
 *    1) Use the MWPF_PIXELVAL native format when calling GrReadArea, in
 *       which case we have to have enough spare room to hold 32-bit
 *       pixlevalues (hence the default MWPF_TRUECOLOR0888 format), or
 *    2) Will use some other PF_* format, in which case the application
 *       is well aware of which pixel-format it uses and can avoid the
 *       device specific RGB2PIXEL and use RGB2PIXEL565 etc. instead,
 *       and specifiy the pixel fomar as MWPF_TRUECOLOR565 etc. when
 *       calling the GrArea function(s).
