Description:
------------
Contrary to 4.3.4 change log

Fixed width/height detection of bmp images using 
getimagesize() function on big endian systems and added 
code to retrieve bmp bit depth. (Ilia)

I still receive incorrect output when querying a local 
.bmp.

Expected result:
----------------
When queried with imagemagick identify verbose returns

Image: example.bmp
  Format: BMP (Microsoft Windows bitmap image)
  Geometry: 800x560
  Class: DirectClass
  Type: true color
  Depth: 8 bits-per-pixel component
  Colors: 56670
  Filesize: 1312kb
  Interlace: None
  Background Color: white
  Border Color: #dfdfdf
  Matte Color: grey74
  Iterations: 0
  Compression: 
  signature:

  Tainted: False
  User Time: 0.0u
  Elapsed Time: 0:01

Tested with 20 or so similar sized bmp file same problem 
occurs.


Actual result:
--------------
 files output using getimagesize returns

array(5) {
  [0]=>
  int(36700960)
  [1]=>
  int(1572865)
  [2]=>
  int(6)
  [3]=>
  string(33) "width="36700960" height="1572865""
  ["mime"]=>
  string(9) "image/bmp"
}
