Marcel Metz 21b5f685e8 Add test image to check loading of grayalpha PNG images with tRNS
A test image with 8-bit grayscale colorspace and simple alpha palette
(tRNS chunk).  Generated with ImageMagick (version: 6.9.9-38 Q16) by
invoking:

```
convert -size 64x64 xc:transparent \
  -stroke Firebrick -fill tomato -strokewidth 2 \
  -draw 'translate 32,32 circle 0,0 32,0' \
  -colorspace Gray -depth 8 \
  -density 28.35 -units PixelsPerCentimeter \
  grayalpha-with-tRNS-chunk.png

Boost.GIL is a part of the Boost C++ Libraries.

The Boost Generic Image Library (GIL) is a C++ library that abstracts image representations from algorithms and allows writing code that can work on a variety of images with performance similar to hand-writing for a specific image type.
