Not sure if this will roll up correctly, but here goes.  There are responses 
here to both Ronald and Tacvec.

Yes i've starting doing this for other ports and agree this is needed.  I'll 
make sure to align version numbers in future builds.

Tacvek guessed correctly, most of my (windows) code is in windows based 
source control and i have not established any version control for linux 
ports other than tar.gz uploads to http server.

Rather than introduce noise to enigma dev signal, i managed to get the 
latest trunk of 1.10 (compatibility branch?).  First off, wow! The 
performance improvements are great.  For example Enigma 1 - Security Guards 
levels was unplayable (probably 1 fps) on 1.01 source, however now it is as 
smooth as i could hope for.  I have noticed similar smoothness in gameplay 
throughout all the levels.  Great work!

I reapplied the most crucial changes which are very simple now that i dont 
even need to remove world collision animations.

There are two areas i needed to modify, the SDL_MOUSEMOVE event logic in 
order to respond correctly to touchscreen input,
and the hardcoded key bindings.  Maemo has hardware buttons which are 
equivalent to ENTER, ESC, F4, F6, F7, and F8.

Heres my first attempt at a diff file, which i manually cleaned up so i hope 
its machine readable, otherwise its human readable.  Perhaps you can 
integrate the global variables through some sort of build configuration.

As I mentioned above I am more than happy with the speed!  This does in fact 
seem to make 100% of the levels playable.  This will require extensive 
playtesting which i am more than happy to help out with :)

Is there any timeframe in mind for when an official 1.10 release will occur? 
Also is it considered bad practice for downstream developers to release 
builds based on svn developmental builds?  If this varies by project, what 
is enigma dev policy on this?  Since the performance improvements are so 
great it will be tempting to get it out in the 'wild'.

Yes, thanks to Daniel Heck and all the level designers... there is much 
personality in the game and level design, and it really draws you in to see 
what nefarious devices are in store for poor blackball next :)

I hope the simple changes i submitted above are of use upstream.  It would 
allow maemo compatibility via basic touchscreen and 4:3 use on maemo. Till's 
tilt modifications and or true widescreen modifications would be separate 
and in addition to something like this.

Thanks again, let me know if you need anything else.
