     Build with lens<4.

     This fixes up changeset 7f3ed3166913133cb0f97d89356b4ff7ee8531fb

     Avoid warnings with lens-4.0

     This change will cause warnings when compiled with lens<4; I did 
not feel it was worthwhile using CPP to avoid this

     Fix behavior of rlabel with VTA_BaseLine.

     This fix is most noticeable with rotated labels.

commit e1149213a15467cd63a7ee75b11cba023fe4614b
Author: Tim Docker <tim at dockerz.net>
Date:   Fri Mar 14 09:03:01 2014 +1100

     The test reference images are out of date, and depend on external
     libraries (eg cairo and diagrams) for pixel accuracy. So, I've
     removed them - the existing harnesses can be used to generate a
     set of test images as required.

     Updates to allow Chart-diagrams to build with latest diagrams release

Author: Douglas Burke <dburke.gw at gmail.com>
Date:   Thu Mar 13 08:27:13 2014 -0400

     BUGFIX: VTA_BaseLine was not supported by rlabel.

     Also added a number of test cases (misc1b to misc1g) which show 
that rotated labels with VTA_BaseLine are not displayed correctly. No 
reference files for these tests have been added.

     This reverts commit 2ee07b29d549c605e245a08379fa0890dbadf368.
