added BM_mesh_elem_flag_enable_all (only had disable function), and add
argunt for vert/edge/face type.
use these functions from EDBM_flag_enable/disable_all (had duplicate
code).
* use polygons for selection (was using tessface)
* ensure tessfaces are created
* mirroring was commented as BMESH_TODO, but api calls now work so add back.
`_set` suffix was used in two ways (confusing)
* to set a flag to be enabled.
* to set a value passed as an argument.
now use enable/disable rather then set/clear for functions which change flags.
also remove BME_weld.c, the file didnt contain much code and the current extrude works well
* add DM_to_bmesh_ex, DM_to_bmesh for converting a derived mesh to a BMesh (rather than a BMEditMesh)
* have a generic variable for allocsize: bm_mesh_allocsize_default, rather than copying the values about.
Issue was caused by making and loading editMesh in drop_named_image_invoke,
which lead to freeing/changing pointers used by CustomData layers. Some of
this pointers might be used by DerivedMesh, so we need to update DerivedMesh
after loading EditMesh.
These changes are to make the bmesh api more consistent and easier to learn, grouping similar functions which is convenient for autocomplete.
This uses similar convention to RNA.
* use face/loop/edge/vert as a prefix for functions.
* use 'elem' as a prefix too for functions that can take any type with a BMHeader.
* changed from camel case to underscore separated (like RNA).
Problem was in how file selector is called by the effect_strip_add operator invoke. WM_operator_filesel() is not suited, as it directly calls exec if filepath is already set, and sequencer_generic_invoke_xy__internal() will set that path unless otherwise told. So using rather the same way to do as the one used by the other "strip_add" operators...
this commit makes vertex paint check if it needs to rebuild the modifier stack when painting.
- when painting with no modifiers, do partial updates from polys to tessfaces while painting, skip re-tesselation.
- when painting onto a modified mesh, dont bother adjusting tessface colors - since the modifier stack will do this anyway.
both cases should be faster then before.
Issue was caused by not enough threshold limit used for removing doubles.
Switched to adoptive threshold value calculation based on smallest length
of segments in meridians and parallels.
Select Linked operator was setting Limit by Seams property automatically
depending on current selection mode. But this property only used to be
set to truth if selection mode is set to Face, in other cases this property
is being reused from previous operator run. This leads to incorrect
behavior of selecting linked in vertex mode after this operator was
used in face selection mode.
In fact all list templates used to block mouse scroll. It's because mouse
scrolls list's scroll bar. But mouse scroll also used to be "eaten" even
if there's no scroll in list template.
This commit makes scroll even be ignored by list templates if there's
no scroll bar on list.
