This commit uses the latest assembler from here:
https://github.com/adobe-flash/graphicscorelib/blob/master/src/com/adobe/utils/extended/AGALMiniAssembler.as

Note to self: the repository and path from above is the version that is to be used in the future. According to Adobe, this single class will always be updated so that it supports all profiles.
