All small API maladies

[WojciechBarczynski]

This issue is a place to put all small changes that should be made to improve the usage experience, however, they are not currently the priority (but shouldn't be forgotten).

List:

• Component IDs must be unique across all outputs (output_1 and output_2 can't define some_comp_id simultaneously). This is unnecessary, but with the current implementation, the user receives an error once they want to do it.
• width, height, top, and bottom should be supported by more components. Users often need to warp components with view to achieve the desired layout.
• Scene validation errors are not returned in response if the request is scheduled, they are logged instead.
• Errors in complex scenes are hard to read, as there is no indication in which specific place they occur. If you get an error like: failed to deserialize ... it's hard to debug it in more complex scenes.
