• Adds .SetShaderBlend(nameA, nameB, blendFactor) to blend between two palettes
• Adds .SetShaderIndex(paletteIndex) to apply the palette to a palette index. This can be used to blend between two palettes if you use a number with a fractional part e.g. a palette index of 1.5 will perform a 50% blend between palette index 1 and palette index 2
• Adds .PaletteGetIndex(paletteName) in aid of the above
