Bug forwarded from Evince:

"The Story:
I had a pdf-image, that was rotated using pdftk. This image was included in a
pdflatex run as embedded image. The resulting pdf is correctly displayed in
Adobe Reader, but within Evince, this image is unrotated (off be 90°)...
Unfortunately I cannot give the example, but I'll try to come up with a
test-file within a few days...

For now, my analysis of the pdf shows that there is the following sequence
within the pdf:
12 0 obj <<
/Type /XObject
/Subtype /Form
/FormType 1
/PTEX.FileName (C:/the/path/to/rotated_picture.pdf)
/PTEX.PageNumber 1
/PTEX.InfoDict 28 0 R
/Matrix [0 -1 1 0 0 596.25]
/BBox [0 0 596.25 843]
/Group 13 0 R
/Resources <<
/ExtGState <<
/s5 29 0 R
.....

My guess would be that Evince does not correctly parse the /Matrix for the
XObject, as the Matrix
0 -1
1 0
would correspond to the missing rotation...

Best regards,
Chewi"

Test case is attached to the original bug report. I confirm it works
with splash.

Indeed, we are ignoring the TransformationMatrix from the state in
CairoOutputDev::BeginTransparencyGroup. Caching the state->getCTM() into
a cairo_matrix_t and then calling cairo_set_matrix with this matrix at
the begining of CairoOutputDev::PaintTransparencyGroup works when scale
= 1 but (not surprisingly) does not scale properly when rendering at
bigger scales.

fix ctm when painting groups

Patch to fix. Similar to the set soft mask bugs we need to store the
current ctm during beginTransparencyGroup when the group is created and
use this ctm when painting the group.
