+Subject: [PATCH] Set alignment for rendering to default
+
+Previous aligning to 32 bytes rendered EPS in wrong way (not always but often).
+Setting default alignment which aligns to size of pointer fixes this issue.
+
+The commit which set it to the 32 was talking about alignment of 4 bytes so I guess
+that there were bits interchanged with bytes.
+
+Fixes #44
