    targetNotReady: 2;
} = ...

How a frame demand finished.

See mln_render_result in the C API reference.

Readonlyfailed: 4

The session failed, and RenderSessionHandle.getFailure() reports why. Once RenderSessionHandle.release() completes, you can attach a new session.
ReadonlynoUpdate: 1

The map had nothing new to draw.
Readonlyrendered: 0
Readonlysuperseded: 3

A later demand with the same flags replaced this one.
ReadonlytargetNotReady: 2

The target couldn't take a frame, such as while a window is hidden or destroyed, or after RenderSessionHandle.releaseTarget(). Demand a frame again later.
