Double check patch again, since my wrong logical thinking,
Every width must be considered to rounding up fiting 8 bits.
this new compuation must be correct.

wbmp format doesn't have any tags for verifying file header,
It's easy to pass other format headers if they have the first 1 byte 0x0,
This ocassionally brings wrong result (= succeeed loading image),
if unknown file format is tried.
So, to make it sure, here verify the size of image additionally.
if the image size is not expected, It returns fail as the result.
This problem is actually happened in this scenario.
open any mpeg file with elm_image.
elm_image_file_set() will return true though it fails to read data.
since wbmp make it pass to succeed.
