The `Image.gl_load()` call was changed in Blender commit
7ad802cf3ae500bc72863b6dba0f28a488fce3d1; the two parameters we were using
were removed.
This commit fixes the exception and makes the texture browser usable again,
but doesn't properly fix everything. The textures are drawn in the wrong
colour space, which will be fixed in another commit once I know how.
When using Blender Cloud Add-on 1.12 or older, Flamenco Server will
automatically convert the Manager settings to version 1. As a result,
upgrading is recommended but not required to keep working with a newer
Flamenco Server.
The frame chunk size has a slightly different meaning when rendering
progressively (Flamenco Server can choose to chunk more frames together
when rendering a low number of samples).
Any 'Create Video' Flamenco task that's part of the job will pad the video
with black pixels to make the dimensions even, and this warning notifies
the artist about this.
This button can be enabled in the add-on preferences and and then be
available on the Flamenco Render panel. Pressing the button will
silently close Blender after the job has been submitted to Flamenco (for
example to click, walk away, and free up memory for when the same
machine is part of the render farm).
Rendering ranges of sample chunks only works reliably for us after
Blender commit 7744203b7fde35a074faf232dda3595b78c5f14c (Tue Jan 29
18:08:12 2019 +0100).
Flamenco Server changed from expecting a fixed number of sample chunks to
a compile-time determined number of nonuniform chunks. The artist can now
influence the size of each render task by setting a maximum number of
samples per render task.
We shouldn't call any `gpu` functions in background mode. Since the texture
browser will never run when Blender is in background mode anyway, we can
simply assign `None` instead.
