dolphin/Externals/wxWidgets3/include/wx/quantize.h
Soren Jorvang d14efe561b Import r67258 of the wxWidgets trunk, which I expect will before
long become wxWidgets 2.9.2, which in turn is expected to be the
last 2.9 release before the 3.0 stable release.

Since the full wxWidgets distribution is rather large, I have
imported only the parts that we use, on a subdirectory basis:

include/wx/*.*
include/wx/aui
include/wx/cocoa
include/wx/generic
include/wx/gtk
include/wx/meta

wxQuantize() {}

//// Operations
// Reduce the colours in the source image and put the result into the
// destination image. Both images may be the same, to overwrite the source image.
// Specify an optional palette pointer to receive the resulting palette.
// This palette may be passed to ConvertImageToBitmap, for example.
// If you pass a palette pointer, you must free the palette yourself.

// This version sets a palette in the destination image so you don't
// have to manage it yourself.

//// Helpers
// Converts input bitmap(s) into 8bit representation with custom palette
// in_rows and out_rows are arrays [0..h-1] of pointer to rows
// (in_rows contains w * 3 bytes per row, out_rows w bytes per row)
// fills out_rows with indexes into palette (which is also stored into palette variable)
