A huge optimization that ensures only the parts of a node graph that have
changed get pushed to the renderer. For thread-safety, the node graph is
copied elsewhere so that users can make changes asynchronously and the graph
can update when its threads are ready. Up until now, if an input value changed,
every node's values would be re-copied, or worse, if a connection was changed,
the entire graph would be recopied. This has been negligible in testing since
we've been largely testing with small graphs, but for massive projects, it's
important that this be as optimized as possible.
This system was kind of janky anyway. It makes more sense ultimately for the
audio management classes to contain the file handle rather than the renderer.
This required various changes to various parts of the infrastructure (mostly
using paths to finding the "root project" of any given object throughout).
Now theoretically infinite projects can be opened and accounted for at any
given time.
This framebuffer was an early approach to the pixel sampler that never got
used, but was still getting created/destroyed unnecessarily. This has now
been removed.
Implements an extra widget to display images on a separate monitor. Both
viewers have separate display color controls since different monitors may
conform to different standards/transforms.
Updates drag mime data to include a variable determining which streams are
enabled and which ones aren't (a binary qint64 where the 0s are disabled
and the 1s are enabled) rather than relying solely on the stream->enabled
values which can't be modified as part of the drag process.
Since other parts of the UI use OpenGL (through Qt), the viewer's context can
sometimes become non-current until the next time it draws. Since the color
processor is created before the main drawing function, the context could
occasionally be non-current causing its creation to fail. Subsequently trying
to use that color processor would trigger a segfault. This commit addresses that
by always making the context current before creating the color processor shader.
Minor optimization, now that the FootageViewer's nodes are
connected/disconnected as part of the process, the second call to invalidate
is unnecessary and will only serve to re-invalidate actually valid cache data.
Fixed bug where code erroneously multipled by full channel height. This is an
incorrect assumption since the full range of -1.0 to 1.0 is 2.0 which means the
difference needs to be halfed to create a range from 0.0 to 1.0.
