The original issue is that we were changing the camera shiftx
temporarily for the stereoscopic calculation. However we are using the
evaluated object when calculating the projection matrix.
Note: Camera framing drawing for stereo still seems to be broken.
But the viewport itself is now correct.
Debugging the edit mode selection I realized the vertices are often
occluded by edges with the same depth. Sometime it can be the center
pixel of a vertex point and that can lead to some selection issue.
So I increased the offset a bit for the vertices and it seems to fix it.
This makes it more future proof and remove baked id offset inside the vbos.
Instead we add the offset as a uniform. This makes it possible to reuse
the vbos instead of discarding them all the time.
Also using batch request may reduce batches creation time.
TH_BACK was being used when drawing the 3D view even though
there was no way to set the color in the preferences.
The color was zero'd when moving to the new 2.8x theme.
Having both gradient and background colors was confusing,
especially having to use 'TH_HIGH_GRAD' for the 3D view, 'TH_BACK' for
other views.
Move the background color back to 'TH_BACK', 'TH_BACK_GRAD' is used
when gradients are enabled.
RNA is unchanged so presets don't need updating.
* 2D Animation: lots of changes from the grease pencil team. Properties
editor layouts, brush and material settings, and more.
* 3D Viewport: wireframes set to 1.0.
* World: use nodes by default.
* Node Editor: use narrow toolbar.
In blender 2.8, when you zoom in, the adaptive subdivisions appear earlier than previous versions.
The grid still appears a little before the snap, but since it is very small I see no advantage in snap for this case.
This commit makes it so curve path parent solving accepts an explicit
arguments for both time and curve speed flag, making it so we don't
have to mock around with scene's frame.
One unfortunate issue still is that if the instancing object is used
for something else, we might be running into a threading conflict.
Possible solution would be to create a temp copy of an object, but
then it will be an issue of preventing drivers from modifying other
datablocks.
At least the original issue is fixed now, and things behave same as
in older Blender version. Additionally, the global variable which
was defining curve speed flag behavior is gone now!
