Add a pixel test for JPEG 2000 image decoding.

Try to draw 4 JPEG 2000 images into the quadrants of a page. The 4
images are all full of red pixels. They differ in the following 2
attributes, and combine to test all combinations of these 2 attributes:

1) Whether the image is JP2 or J2K.
2) Whether the image dictionary has a /ColorSpace entry.

Suppress the test results since the test does not pass yet.
