=> R0 = flags
R1 = redraw block (r_bpp)
R2 = address of source palette
R3 = address for dest palette (needs 4*R4 bytes preserved)
(source may equal destination)
R4 = number of palette entries (eg 16)
<= R0 and flags corrupted
This SWI is used to create the r_palette data block. If R0 = 1 on entry
then it takes a palette consisting of a list of wimp colour numbers (one per
word) and converts it to entries of the form &BBGGRRxx, a 24 bit palette
entry by using the call Wimp_ReadPalette and
duplicating the nibbles. If R0 = 2 on entry then it takes a list of entries
of the form &BBGGRRxx and converts them to colour masks required for DSA
redraw (see r_palette) using ColourTrans calls and
ZapRedraw_GetPaletteEntry. If R0 = 3 on entry then it does both, converting
wimp colour numbers to DSA redraw masks.
