 With the old team colour system, the team colour chooses which frame is
 loaded out of a texture animation. If the object in question uses the
 animation instead of team colour (e.g. explosions and VTOL jets), '''the
 starting frame is still set''' based on the team colour. While completely
 unnoticeable usually, the attached mod makes the problem rather obvious,
 since the rotor blade animation has 3 frames out of a possible 4 which
 could be used on the texture page it uses.

 The top left of the image is where the animation should start, as defined
 in the modified effects\fxvtl01.pie and the animation has 3 frames, before
 it should start on frame 1 again. (Should go: top left, top right, bottom
 left, top left, top right etc.)

 However, if playing as the orange team colour (team colour 1), the
 animation will start on the top right, then go to the bottom left and then
 continue to display the bottom left for another frame, before going back
 to the top right and repeating.

 Team colour 2 (grey) will then start on the bottom left, then display
 bottom left for a second frame and then display top right.

 Team colour 3 (black) will start on the top left, but only because the
 starting frame has reached the end and started back at the beginning. This
 then repeats, with all of 0,3,6 and 9 starting at the top left and looking
 correct, while all other team colours look incorrect.

 This may or may not be a problem only associated with the VTOL jet
 animations, I don't know whether it actually effects other animations such
 as explosions, since I don't know if they inherit team colours from
 whatever is firing them etc.

 To test this, the attached mod replaces the viper body with BP's scavenger
 helicopter model and the viper body's VTOL jet animation with my custom
 rotor blade animation, so all you need to do, is create a viper VTOL and
 move it so that the animation is displayed. If tested with green, black,
 pink and purple it'll seem to work as intended, any other team colour and
 one of the frames will be displayed twice as long.

 (note that the forth place on the texpage (which would be displayed if the
 animation had 4 frames) is not shown and instead, the previous frame is
 displayed twice as long)
