Instead of having to maintain manually the map file for LD with the list of symbols that we want to keep in the WRaster library (the purpose is to hide internal symbols), this patch implements a script that parses the public API header and extracts automatically the list of names that are supposed to be visible to the user. The goal is to reduce possible human errors, like for example the function RCombineAlpha that was forgotten from the list, yet still keep the map file feature which is considered a good practice (it reduces the risk for name clash and the risk of mis-use of internal stuff from the library).
