Layer support for globe browsing:
Add layers using the function openspace.globebrowsing.addLayer
Delete layers using openspace.globebrowsing.deleteLayer
Layer type does not necessarily have to be of tile type. For example solidcolor does not use tiles
Blend modes for layers are Normal, Add, Subtract, Multiply, Color
Layer adjustments to affect layers. The current only active one is chroma key to cut out a color from the layer. Transfer functions or clipping masks are examples of layer adjustments for the future.
Support for adding layer specifications for quickly accessing GIBS layers:
openspace.globebrowsing.createGibsGdalXml
openspace.globebrowsing.createTemporalGibsGdalXml
The arguments for these functions are currently strings. Would it be better to use a lua dictionary?
No data values for height layers are correctly regarded (can be seen on Earth. No longer bumps on the poles)
Other minor things:
Worked a bit on point globe to render globes at large distances. Currently not in use and doesn't have anything to do with the other things.
Concurrent job manager takes a thread pool as argument and not a pointer to one. This is because the concurrent job manager needs to have ownership of the thread pool for correct deinitialization. Will cause breaking change for users of concurrent job manager if merged in to master.
