Replace GEOS C++ dependency with hand-rolled snap-to-grid implementation

@manisandro any chance of adding some unit tests for this to testqgis.cpp? |

Added some tests with fancy numbers. |

There was a problem hiding this comment.
Maybe a couple of simple "rounding halfway cases away from zero" tests? Just to make sure no one accidentally borks the implementation later on. e.g.
QCOMPARE( qgsRound( 1.5 ), 2. );
QCOMPARE( qgsRound( -1.5 ), -2. );

Added halfway test cases. |
