In some cases it was not working well.
Opengl was using an other algo (using the curve properties to create segments)
Now only the OpenGL algo is used,
with optimization to reduce the number of segments.
Before the refactor library browser display Bezier curves correctly only
once, at other times they were just straight lines or crashed the
application.
* Added modified version of FindwxWidgets.cmake to prevent manifest build and link errors
with VC8.
* Fixed ambiguous math function ( sqrt, atan, cos, etc. ) call errors when building
with MSVC.
* Moved bitmap copy bitmap source file destination to the build path to prevent source
tree pollution and library rebuilds when building on different platforms.
