hi. every one

Android Frameworks's alpha blending is not working correctly in
semitransparent.

For example, Blend semi-transparent surface with opaque background
picture.

The final result value of alpha is not 0xFF.

If framebuffer's color mode is rgb565.
This problem does not appear.
but, my framebuffer's color mode is ARGB_8888.

My solution is to assign every Framebuffer's pixels's alpha value to
0xFF.
but, it's slow.
