5cd1ca13c5 Fix item global matrix error (#1562) 
Bug happen when item is drawn after an empty symbol that should be drawn
in a separate canvas context (partial opacity or special blend mode).
As bounds are empty, symbol drawing process is interrupted but its
global matrix is not removed from the stack.
Closes #1561

74bb49d8c0 fix issue with svg import of raster images 
When importing rasters after load if the image has a matrix with any translation/skew value
the image will calculate the wrong matrix after loading.

In order to correct this we append the translation rather than prepend so
that it happens in the correct order relative to the transformation.
