Describe the bug

It seems that the processing is different between MUGEN and IkemenGO. It's difficult to explain, so please watch the video.

To Reproduce

  1. Open "Mountainside Temple" stage def file.

  2. Add the following to the last line: [bg] type=p actionno=1 start=,120 width=300,300 scalestart=.5,.1 layerno=1 [begin action 1] 0,0,0,0,1800 interpolate angle 0,0,0,0,0,,,1,1,-360

  3. Check the processing results with the engine.

I think this has to be order of scaling and rotation. In MUGEN, the rotation is done first, then scaling is done. In IKEMEN, the scaling is done first, then rotation is done. This is ordering issue and it's easy to fix. (if the rendering engine allows to change the order of translation)
