Syntax:
b2dGetImagePaletteColorA:Int(imageHandle:Int, index:Int)
Int
Returns the alpha component of a palette entry, 0 to 255.
Takes imageHandle and index (0 to 255).
Returns the alpha value, or 0 if the handle or index is invalid.
Reads the stored palette. Note this is the entry's own alpha - it does not account for a hole punched by b2dSetTransparentIndex.
