Simon Hausmann 03bef6dba3 Fix casting with conditional expressions 
The following scenario would fail compiling to C++ because we failed to
determine the return type of the conditional expression:

    Test := Rectangle {
        property<bool> condition;
        property<color> extra_color;
        color: condition ? root.extra_color : 4289374890;
    }

The type of the true branch would be color and the false branch would be
a float. Since they "disagree", ty() on the expression would return
Type::Invalid. This was temporarily worked around in the C++ generator
by always returning the type of the true branch, but that's wrong.

Instead this patch changes maybe_convert_to to apply the Cast expression
to the individual branches, placing the cast only to the numberic
literal and correcting the return value of ty() on the conditional
expression.

SixtyFPS

This is the monolithic repository of the SixtyFPS project.

What is SixtyFPS

It is a GUI engine, with libraries for different languages. The aim of the project is to be

  • Lightweight: We aim to provide a runtime that fits in a few MB. Minimize the RAM usage, and also be blazing fast.
  • Straightforward: We want to optimize as well for programmer and designer productivity. Making it an enjoyable experience to work with. We claim to use well thought idiomatic API for each target language. Provide well written documentation. And use of modern tools.
  • Native: We support many platforms. From embedded devices, to desktop, including mobile and web. One should feel at home on each platform. Both the user and the developer. The appearance and look and feel should match was is expected of an application build for this platform.
