The issue actually goes a bit deeper, converting curve to mesh will
change texture space just because font and bezier curves are using CV
to calculate texture space.
So now when those objects are converted to mesh, we disable auto
texture space and copy evaluated space over.
Original fix was assuming that particle init operation is updated on every
frame, which is wrong behavior and that was fixed in previous commit to the
original bugfix.
A comparison should have not just have been against an epsilon,
but relative to the edge length involved.
Thanks to mano-wii for patch on which this is based.
The idea is to de-duplicate logic in DEG_id_tag_update() and flushing where we
need to translate depsgraph tag or component type to ID level recalc flag.
Currently unused, but is required for Blender 2.8.
Not only this helps merges form master to the branch, but also:
- Allows us to production-check changes as soon as possible.
- Avoids some unnecessary editors update about ID changes.
- Adds small optimization on queue size by always keeping one of the pointers
outside of the queue.
The idea is to allow iterating over ID nodes in exact order of their
construction, and in order which will not change dependent on memory
pointers or anything.
Currently this is a no-visible-changes change, but the idea is to use this
dedicated flag to tell which exact components of ID changed, make it more
granular than just OBJECT and OBJECT_DATA. Allow setting this field based
on what components new dependency graph flushed on evaluation.
Currently unused, but this is where LIB_TAG_ID_RECALC* flags will go.
Also modified other DNA to make pointer property being followed by pointer.
Makes it easier to keep track of alignment and extend nested structures without
ruining anything.
This is a part of ongoing work in Blender 2.8, where we need to replace
`object->id.tag & LIB_TAG_ID_RECALC_DATA`
with
`object->data->id.tag & LIB_TAG_ID_RECALC`
Should be no user measurable difference.
Previously, hitting Shift-LMB will first invoke selection operator, which
then later on is transformed to mouse tweak used for reroute operator.
This was causing problems extending selection with Shift-LMB when clicking
fast or from a tablet.
