Old code assumes that a NodeParam's parent will always be a Node. The function
has been separated off and tweaked in the event that this is not the case.
Updating values rapidly would cause strange jitters as a
byproduct of the viewer trying to update from the renderer while
it was still working. Rather than the viewer trying to access the
the renderer, we now send textures in the initial update signal
to keep everything synchronized.
Major refactoring work to try sharing as much code as possible between the
video renderers and audio renderers, as well as make them as
platform-independent as possible.
commit
For testing the new iteration, the texture cache disk download was written
into the main thread instead of into the separate threads. Now they're back
in separate threads again.
Also I think some of these files probably should have been in the previous
commit.
specific code
The new rendering system is now starting to work as planned, however it is
still not as complete as the iteration before. But this should be a more
robust design moving forward. Work was also done towards splitting off all
OpenGL-specific worker code into a derived class. The hope is to have no
hard dependency on OpenGL and make swapping it out with other backends
straight-forward.
