AHX player library

[MickGyver]

I made an (experimental) AHX player library for Blitz Basic 2. From my limited testing it seems to work both using a CIA interrupt and calling the play routine each frame. Sharing it here if somebody wants to try it out. Source code for the library and some examples are included.

---        AHX Library for Blitz Basic 2        ---
---       by MickGyver  (Mikael Norrgard)       ---
---------------------------------------------------

This library is based on the AHX replayer example
version 2.3.3. I have only tested this in WinUAE
(A1200, KS 3.1) but it is built using the 68000
version of the replayer. I have included examples
for both a CIA player and a VBL player. Modules can
be loaded as included binary files or as banks.

To use it, copy ahxlib.obj to blitzlibs/otherlibs
and run makedeflibs to rebuild deflibs. The library
number is 196.

Commands:
---------------------------------------------------

AHXInitCIA                
Initialize the AHX player CIA interrupt handler.

AHXInitPlayer             
Initialize the AHX player.

AHXInitModule moduleAddress.l
Initialize an AHX module.

AHXPlaySubSong subSong#   
Play a subsong. 0 = Main/first subsong.

AHXUpdate                 
Call the play routine if not using the CIA.

AHXStopSong               
Stop the currently playing song.

AHXKillPlayer             
Kill the AHX player. Don't forget.

AHXKillCIA                
Disable the CIA interrupt handler. Don't forget.

AHXSubSongCount           
Returns the number of subsongs (.b) in the module.

Great work, I have been looking for Blitz AHX CIA replayer functionality for some time now.

However, it does not seem to be very compatible with the Display library, no matter what I do I just get a Workbench grey screen with a few horizontal black lines scrolling down.

Also it would be nice if a few more of the functions listed in the AHX offsets file were implemented.
