+ GRAPHICAL BUG ADDRESSED BY CHECKING GRAPHICS ENGINE VERSION:
+
+ When using an animation frame delay of 1 (this only happens with
+ "sp_zonk.moving.left/right" in the classic graphics), the default
+ (non-moving) animation shows wrong animation frames (while the
+ moving animation, like "sp_zonk.moving.left/right", is correct,
+ so this graphical bug never shows up with the classic graphics).
+ For an animation with 4 frames, this causes wrong frames 0,0,1,2
+ be drawn instead of the correct frames 0,1,2,3. This is caused by
+ "GfxFrame[][]" being reset *twice* (in two successive frames) after
+ an element change: First when the change delay ("ChangeDelay[][]")
+ counter has reached zero after decrementing, then a second time in
+ the next frame (after "GfxFrame[][]" was already incremented) when
+ "ChangeDelay[][]" is reset to the initial delay value again.
+
+ This causes frame 0 to be drawn twice, while the last frame won't
+ be drawn anymore, resulting in the wrong frame sequence 0,0,1,2.
+
+ As some animations may already be cleverly designed around this bug
+ (at least the "Snake Bite" snake tail animation does this), it cannot
+ simply be fixed here without breaking such existing animations.
+ Unfortunately, it cannot easily be detected if a graphics set was
+ designed "before" or "after" the bug was fixed. As a workaround,
+ a new graphics set option "game.graphics_engine_version" was added
+ to be able to specify the game's major release version for which the
+ graphics set was designed, which can then be used to decide if the
+ bugfix should be used (version 4 and above) or not (version 3 or
+ below, or if no version was specified at all, as with old sets).
+
+ (The wrong/fixed animation frames can be tested with the test level set
+ "test_gfxframe" and level "000", which contains a specially prepared
+ custom element at level position (x/y) == (11/9) which uses the zonk
+ animation mentioned above. Using "game.graphics_engine_version: 4"
+ fixes the wrong animation frames, showing the correct frames 0,1,2,3.
+ This can also be seen from the debug output for this test element.)
