Description

A test using color PNG images. There are four columns of images over a blue background; from left to right they are
  1. Full color PNG
  2. Full color PNG with alpha; the outer part is fully transparent and the circular part is partially transparent.
  3. Indexed color PNG
  4. Index color PNG with transparency

There are two rows of rectangles using these PNG images as textures; the images and rectangles are all 200x200. In the upper row the transparency is set to 0.0F and in the lower row it is set to 0.3F. For columns 1 and 3 (without alpha) the lower image renders differently because the Material2D transparency is used; which is not the case for columns 2 and 4 where the image alpha overrides this. Hence in columns 2 and 4 the upper and lower rendered output is the same.
