180295936b Use guigfx.library for 8-bit image quantization 
This achieves speed-up on OS3/68k platforms where 8-bit modes are more likely to be used, at the expense of lower quality quantization than the former picture.datatype abuse provided.
Additionally, caching of BitMaps in palette-mapped modes is now possible.
NetSurf now requires guigfx.library (and render.library) in order to start, even on OS4.

c0d031bf73 Make the palette-mapped state relate to the rendering layer rather than globally. 
This means we can still render in 32-bit mode internally when the destination isn't the screen.
NB: bitmap_render is currently freezing when the screen is in palette-mapped mode (old bug, pre-dates this change), so for now we skip this routine in that scenario.

b41685208f Revert "alloc bitmap structures using itempools" 
This reverts commit 0cc19b10fc.

This caused memory leakage, as the memory pool is removed before the core has destroyed all the bitmaps.

c8caf08ef1 As the content interface is now doing the scaling, we render to a native BitMap and then copy that to the RGBA32 bitmap buffer without re-scaling. 
The native BitMap is currently discarded and will be re-created when it is displayed.
