In qt4 qreal is defined as float on arn* while on other architectures it
is defined as double. Assignments between qreal and double are OK
because assignedments between float and double are ok. However careless
mixing of qreal and double can cause problems in various situations
involving pointers, references, temperlates or function overloading.
I've applied the trivial fix (typecast the constant 1.0 to qreal) and
i'm now running a test build to see if there are other similar issues.
I'll follow up with a patch when i've either achived a successful build
or given up.
For qt5 qreal is now defined as double on all platforms but it's way too
late for a similar change in qt4.
