Bugfix: Renderer: Primary program loses uniform binding of rootBuffer
when models/textures are uploaded during play. Also, cleanup of
ensureInit().
ThreadManager: Delegated render and wait attempts to separate method to
elminated labeled break. Bugfix: Render attempt at deadlock when waiting
for GPU access tasks to finish because some rely on GL tasks as well.
Cleanup: Consolidated deque peek/remove with pollFirst().
Renderer is now activated immediately at startup to make way for loading
screen.
WorldObject.initializeObjectDefinitions() now within a gpuMemAccess
task.
