Per https://bugs.chromium.org/p/chromium/issues/detail?id=597127#c28 some images that reproduced  bug 597127  would be useful for our testing.

I provided red / green / blue square images from Blink to the reporter of  issue 597127 , and asked that they use their system to munge them into new images that exhibit the bug, and send them back to me.

The reported used ImageMagik to create the test images, and they look fine to me.

Add Progressive JPEG YUV decoding layout tests

See also  issue 597127 . Use a <meta> viewport tag to force
GPU rasterization on the Android bots where supported and
add test cases for images and for the <canvas> element:

  fast/images/jpeg-yuv-progressive-image.html
  fast/images/jpeg-yuv-progressive-canvas.html

Add new Progressive JPEG image resources: they were built
using the ImageMagik

  % convert -size <size> plasma:fractal -paint

command. Details of the JPEG image encodings are:

ycbcr-progressive-000.jpg

Progressive DCT, Huffman coding
Bits Per Sample	8
Color Components	3
Image Size	200 × 200
Y Cb Cr Sub Sampling	YCbCr 4:4:4 (1 1)

ycbcr-progressive-001.jpg

Progressive DCT, Huffman coding
Bits Per Sample	8
Color Components	3
Image Size	250 × 250
Y Cb Cr Sub Sampling	YCbCr 4:4:4 (1 1)

ycbcr-progressive-002.jpg

Progressive DCT, Huffman coding
Bits Per Sample	8
Color Components	3
Image Size	300 × 300
Y Cb Cr Sub Sampling	YCbCr 4:2:0 (2 2)

ycbcr-progressive-003.jpg

Progressive DCT, Huffman coding
Bits Per Sample	8
Color Components	3
Image Size	350 × 350
Y Cb Cr Sub Sampling	YCbCr 4:2:0 (2 2)

Note: the progressive images with YUV 4:2:0 encoding both
cause the bug reported in  issue 597127 .

The new tests added in this CL provide some test coverage
for  issue 597127  (run with --force-gpu-rasterization) but
more work is needed to automate that on the bots, such as
with a virtual test suite for this flag (it has none).
