Description: Fix qreal VS double issues.
 This patch tries to fix qreal VS double issues for ARM

 There are two seperate issues, the first is trivial just a typecast on
 a const.

 The second is however less-trivial and needs to be checked
 before merging. sip doesn't seem to like the type
 QVector<double> on platforms where qreal is float but changing
 the type to qreal may have knock-on impacts on the native code.
