Qwt 6.0,2

After a maintenance release for Qwt 5.2, this is the update for the Qwt 6.0 branch.

Qwt 6.0.2 is a pure maintenance release collecting all bug fixes that happened since Qwt 6.0.1. It is binary compatible with all other Qwt 6.0 releases.

Qwt 6.0 is not intended to be compatible with Qt 5 - this is what Qwt 6.1 will offer, what is expected to happen soon after Qt 5.0 is available ( about the end of this year ).

Its key features are a floating point based render engine for QwtPlot and template classes for implementing new types of plot items.

Qwt 5.2.1

Qwt 5.2.1 is a maintenance release with a couple bug fixes. It should be binary compatible with Qwt 5.2.0 on most platforms, but I'm not 100% sure about Windows because some pointless declarations for exporting templates have been removed from the headers.
