Added basic javascript stuff for depth buffering
minor changes
Depth buffer now being sent from simplejob.
Pipe is up for transferring depth buffer to texture in javascriptcode.
Only getting 10 first depth buffers
Commenting mostly
Merge remote-tracking branch 'origin/jnygaard_depth_buffer' into jnygaard_depth_buffer
More 2.5D-stuff...
Splatting without using the depth buffer seems to work.
Splatting + depth buffer kinda works, but unprojecting not done yet.
...
Transformations work. Cleaning up after this commit.
Checkpoint. Proxy working but not yet parallel to image-from-client...
Some bits needed for depth+rgbImage in place. Cleanups.
Working state, but image+depth path not in place yet.
Merge remote-tracking branch 'origin/kjetilly_deadlock_fix' into jnygaard_depth_buffer
Added a hopefully helpful message for the case that we couldn't get a WebGL-context
Verified working state
Snapshot response is now wrapped as a JSON object, with fields "rgb" and "depth".
(The rgb is passed on to the ProxyRenderer, but is not yet been made use of there, so proxy geometry is not properly colored.)
Proxy splats now colored with the last available snapshot rgb image
