9fb2270f58 improve Pixel_in_screen_overlay_with_opt_preview() (Mode5/Raster) 
now it is possible to paint in layer 5 with one of the color
defined as INK 0 to 3 in one of the first 4 layers.

implement C64 HiRes constraints. 
As they are almost the same as ZX Spectrum, that was easy.

9d46d1e90f Implement a more generic "rasters" mode for CPC 
This is similar to mode 5, but with less constraints:
- All inks can have split rasters
- Split rasters have a min width of 32 pixels

Note that this is nowhere near enough to make sure the image will be
renderable (number of colors should be limited, unless there is a span
without rasters allowing to reload registers with new colors, and
moving from one pen to another also has a cost). The goal is to offer no
over-restriction (everything that can be shown on the real machine is
drawable). Additional constraints may be checked from a lua script that
will generate the code and data for displaying the picture.

enclosing the unquantized area.

aef77744e1 EGX mode for CPC 
In this custom mode, odd lines use MODE 0 (wide pixels, 16 colors), and
even lines use MODE 1 (square pixels, 4 colors).

- Add a settings window to the 8-bit effect where you can chose what you
want to draw
- Add the customizations required to make it work in graph.c
- Tweak some other places so it is easier to add other modes later on.
- Groundwork for some more modes: EGX2, ZX spectrum, Game Boy color.

23eded3e09 Fix endless event loop in Haiku 
SDL for Haiku always send a WM size change at init. We did catch that it
would not cause any SDL mode set, so we ignored it, but we forgot to
reset the resize width and height. So each run of the event loop would
try to resize the window again and again to the same size.

Thanks to event throttling this was not very noticeable, the main
consequence was that some stuff was reset and for example the tooltips
in the status bar were not showing at all.

878c926ce4 Fix issue 185 (XOR highlight) : 
* Use a simple optimization algorithm to compute a good set of XOR color pairs
 * Algorothm is not very optimized (complexity is up to n^3). In practize, it stabilizes after 2 to 3 rounds of swapping colors
 * Use this color table for all XOR effects
 * Setting for grid color is now removed
