Subject: [E-devel] [PATCH][EDJE] Patch to remove the alpha from image
header while saving if the alpha is set to 1 but the image is fully
opaque

Attached to the mail is a patch to set the alpha information for an
image header to 0 with alpha present but all the texels being opaque.
Continuing to our discussion, as suggested by many people in the
community it has been implemented at edje_cc level.

Change description:
    While compiling the edc file, image data for image files is
scanned to find out whether the alpha value in header is set to 1 and
is not being used in the image.
  If this is the case, while writing to eet the alpha is set to 0 to
avoid blending for such images in the graphics pipeline when used by
evas.
