Add dynamic framebuffer support. Will probably need further commits to cover changes in the DEF files.

/**
This lookup table is used for outline and shadow fonts. Four entries of this table represent 
the percentage of Outline, Shadow, Fill and Background colour to be used to get the final colour to be 
displayed on screen.

The following formula is used to blend four colours:

blendedXXXColor = (XXXOutlinePenColor * FourColorBlendLookup[index][KOutlineColorIndex] + 
			   		XXXShadowColor * FourColorBlendLookup[index][KShadowColorIndex] +
			  		XXXFillColor * FourColorBlendLookup[index][KFillColorIndex] + 
			  		backgroundColor.XXX() * FourColorBlendLookup[index][KBackgroundColorIndex]) >> 8;
where XXX can be Red, Green or Blue
and index is the 8-bit value which will be provided by the rasterizer to decide which 
entry of lookup table should be used. Right shift by eight will divide the calculated value in % with 
256 to get the actual colour.

This table is provided by Monotype and MUST NOT be changed.
