When copying an image that has alpha channel to the clipboard, the alpha channel is removed. Format of the image does not seem to have an effect in this case, neither Format_ARGB32_Premultiplied or Format_ARGB32 work.

Steps to reproduce:

• Run attached sample
• Press button to create image and copy it to clipboard
• Observe the copied image through clipboard viewer or paste the image to a program that supports alpha channeled images
• EXPECTED: Image is properly pasted / looks ok in the clipboard viewer
• ACTUAL: Instead of alpha channel, the alpha area is totally black
