Animation duration value validation

duration: 0xabc 

The decimal value is 2748 and the following issue is detected as expected:

D:\QtQSR1.2\X_RC3_tests\TC_R2.3.4_Host_Win_10\indicators_R2345\MainForm.ui.qml:-1: error: Animation steps is bigger than SafeRenderer::Constraints::MAX_ANIMATION_STEPS. Transition is ignored.

But if the value is entered without 0x prefix 

duration: abc or duration: äääääää

then the issue is not popping up, and the animation is not rendered.

So it seems that there is no full input data validation.

Negative values are ignored but the warning message is not exactly correct:

D:\QtQSR1.2\X_RC3_tests\TC_R2.3.4_Host_Win_10\indicators_R2345\MainForm.ui.qml:-1: error: Animation steps is bigger than SafeRenderer::Constraints::MAX_ANIMATION_STEPS. Transition is ignored.

Besides the duration type is described as int, which can hold negative values.

The int type refers to a whole number, e.g. 0, 10, or -20.
The possible int values range from around -2000000000 to around 2000000000, although most types will only accept a reduced range (which they mention in their documentation).

Do we have any limitations mentioned for the duration?
