Here is the original png and output swf files. See few artifacts if two images
are overlapped in a single frame. It does not happen always.
Overlap two opaque images
Overlap two transparent png images, see how ogre colors is broken in 1st and 2nd images.
I have inserted same .png image with two separate Shape instance and then reused a shap instance
and placed it to the two positions. 1st one is 65KB filesize and 2nd one is 33KB filesize,
but still colors are broken.
Use different images and overlap images. Ogre text is ok if its toplevel image.
I've tested same image with mingswf package (c++ package with php plugin).
Here we can see how overlapped image is ok and single image color is ok.
Compare colors to the first images and see the difference.
Overlap two transparent test png images, looks ok.
Overlap two transparent png images, some artifacts is seen.
