#11542: Using geometry buffer with integer coordinate type
------------------------------+---------------------------
 Reporter:  jim.whittaker@…   |      Owner:  barendgehrels
     Type:  Bugs              |     Status:  new
Milestone:  To Be Determined  |  Component:  geometry
  Version:  Boost 1.59.0      |   Severity:  Problem
 Keywords:  geometry buffer   |
------------------------------+---------------------------
 Applied the following patch to allow use of buffer when using an integer
 coordinate type. Found in 1_58, also present in 1_59.
