Define the asset runtime allocation type.
You can define the type of memory allocation the platform is going to use when accessing the asset. It is useful if the board has different kinds of volatile memory (for example RAM, VRAM or HyperRAM), or supports different memory allocation strategies.
This property is of integer type and its value has to be greater than or equal to
0 and less than
256. The value has to match the memory allocator types known by the platform, where the range
[128,255] is dedicated to user-defined custom allocators.
If a given target board supports custom runtime allocation types, they will be described in the board-specific documentation.
If not set, the default value depends on the resource cache policy: if the cache policy is set to
OnStartup then it will be
DefaultPreload), while if set to
OnDemand (or the image is compressed) it will be
OnDemand cache policy it's also necessary to enable Image caching.
Source file properties must be set before adding files to the application using the

This property was introduced in Qt Quick Ultralite 2.0.
