+ This feature allows a splashscreen image to be displayed during the

following
+ functionality:
+ - Choice of 80x80, 160x160 or 320x320 default "NX" logos
+ - Alternative "out-of-tree" image as splashscreen
+ - Configurable background colour (default black)
+ - Bit-per-pixel choice (32/24/16/8/Greyscale/Mono) to suit the
LCD used
+ - Splashscreen can be set to remain displayed for 'n' seconds
('n' can be 0)
+ - Splashscreen can be cleared (to black) once framebuffer
device register is
+ complete
+ - Python "splashscreen_converter.py" tool (in NuttX tools
directory) can be used
+ to create custom splashscreens - note the tool restricts the
number of colours
+ to 256.
