Description Paul Sephton 2006-07-19 15:39:24 UTC
Setting the fallback to resolution 300,300 for either postscript or PDF
back-ends appears to change the matrix used for normal line draw, but not for
text rendering.  The problem does not occur unless alpha blending is used
(forcing the fallback)  Using a fallback resolution of 72,72 renders the line
draw at the correct locations.

Re-tested against latest git [master] updates which address surface fallback. 
Problem persists as of 3 August.
