Okay, with this update I am going to declare special behaviors fixed. Even though you might not believe me, because this is the fourth time I am making such a claim. This time I'm dangerously close to what the real game does ;-)

anim.cpp
*) Changed the getOffset accessor to add the default 32 pixel offset if it should be there.

bridge.cpp
*) Because of the change in anim.cpp I could remove the default 32 pixel offset I added earlier.

event.h, event.cpp
*) Changed the overlap method to include the offset if necessary.

eventframe.cpp
*) Changed the step method and removed the default 32 pixel offset I added earlier.
*) Changed the draw method slightly so when offsets should be ignored, that actually is the case.

eventframe.cpp
*) Explosive effect now is more random
*) Changed positioning of special behavior again slightly

Changes to show finishing animations with an explosive effect. (e.g. shown when turtles get shot in Diamondus)

eventframe.cpp
*) The drawing routine no longer ignores negative finish animation values. Instead 128 is added.
*) If 128 is added that means an explosive effect should be used. A boolean is set for this.
*) If the boolean is set the finishing animation will be drawn six times. The animation will be moving in a half circle trajectory.

Various changes to correct the positioning of special behaviors. This time the fix is actually performed properly ;-).

levelload.cpp
*) Undid a change I made earlier. I changed << 2 into << 3, but it turns out I was wrong. This seemed to work due to a bug in eventframe.cpp.

bridge.cpp
*) Removed one tile from the default offset value for bridges

event.h, event.cpp, event.cpp
*) Removed the extraOffset variable I added earlier. It turned out this was totally unneeded.
*) Fixed the way X and Y positions in the viewport were determined. It's a lot simpler now, and I wonder why the previous version was so complicated.
*) More changes to get rid of the extraOffset variable.

Tons of changes to correct the position of event animations in a slightly prettier way than the previous way.
This time the offsets within animations aren't changed. Instead the offsets are changed for each event.

bonus.cpp
*) Changed the method call that disables a default animation offset.

anim.cpp, anim.h
*) Removed method to copy offsets.
*) Refactored method name for the method that disables a default animation offset.

levelload.h
*) Changed the enemy path loading

bridge.cpp, event.cpp, eventframe.cpp, event.h
*) Changed method calls that happen with certain behaviors
*) Added an extra offset that can be set to correct positons.

playerframe.cpp
*) Changed code to understand the extra offset

anim.h, anim.cpp
*) Frame by frame X-offsets are being shifted two bits up now.
*) The animation-wide X-offset has been removed because it does not exist.

levelload.cpp, bonus.cpp
*) Due to the changes in anim.cpp and anim.h the animation loading code had to be changed.

bridge.cpp
*) Bridges should ignore an animation's Y-offset if it is zero.

event.h, event.cpp
*) Added a getAnim method to make life easier.
*) Events with certain behaviors need some fiddling with Y-offsets so they can be drawn correctly.

playerframe.cpp
*) The invincibility animation should also ignore Y-offsets.

Add initial decoding of FF frames. Works with shareware intro. Looks nice with level over, but repeat needs a small fix. 

Enforced case-sensitivity for file names, accessible by defining UPPERCASE_FILENAMES or LOWERCASE_FILENAMES.

Moved guardian energy bars to the foreground. Changed the way post-level bonus levels and cutscenes are launched. Disabled bonus levels in multiplayer.

Changed animation handling so that it does not require a level to exist. Improved bonus level 3D projection.

Created look-up tables for trigonometric functions. Refactored sprite loading. Added sprites to bonus levels.

Enable sound directly after init, not only when playing music.

Updated scene playback with more animation attributes and types. Now playback ][ frames which is full screen frames. Two types of frames missing FF and RC frames. These are the only frame left that are used.
