Qt QML Standalone Application project does not reserve enough heap for QML applications run on Symbian devices

Symbian's default maximum heap size is too low for Qt applications as Qt objects reserve almost everything to heap. Any more complex, non-trivial real world QML application will quickly run out of memory and crash on the device. QML Viewer replaces the default 1MB heap size with 2MB, the same should be done in the project file of the Qt QML Standalone application stub. If application requires more heap than that it has to modify the pro file manually.

symbian {
    TARGET.EPOCHEAPSIZE = 0x20000 0x2000000
    ... 
}
