Disable "birdseye" 3d when quest is selected

[smichel17]

Use case
Specifically for building quests, when you select them, only the base of the building is highlighted. In birdseye 3d (left), it's difficult to see the vertical "corners" of the house when it's ~centered in the screen. This leads to the impression that the rendered map shows things in the wrong position, at an offset. In full 3d (right), this is not a problem, since the left wall is visible (but, the map automatically switches to birdseye 3d when a quest is selected; in the screenshot, I manually tilted it with a two-finger shove gesture.

Proposed Solution

When a quest is selected, and the map is switched back to flat, also turn off birdseye 3d.

What do you mean with "turn off birdseye 3d"?

[smichel17]

Switch to full 2d rendering. Basically #2206 but only for when quests are selected.

edit: tangram calls it the flat camera type

[westnordost]

Okay, this is not going to happen then, since this means that the whole scene is reloaded in tangram-es which leads to a visual jerk, especially on less powerful/old devices.

[smichel17]

The docs mention that

The flat camera is a shortcut to a view which can be produced by the other two cameras, but is simpler to setup and use

I wonder if we could do the "less simple" route of adjusting whichever camera parameters. Would that be possible without reloading the scene?

[westnordost]

I don't think so
