fix/workaround [#36269] Crash upon right click on menu and left click on item

internal change for ui_mouse_motion_towards_*** use,
only run these checks for buttons using the UI_BLOCK_MOVEMOUSE_QUIT flag.
no functional change but makes debugging easier and was calculating mouse motion in relation to some popups for no reason.

dyn-topo: maintain materials for new faces.
also minor optimization for BM_edge_in_face(), check edges radial loops rather then the faces edges
since normally there are 0-2 faces attached to an edge compared to 3+ edges in a face.

internal bmesh api change: BM_elem_attrs_copy() no longer copies the selection flag.
this was slowing down modifiers since the selection flags would be copied and flushed to connected geometry.

code cleanup: use iterator macros, and replace BM_LOOPS_OF_FACE with direct loop access when converting a bmesh to a mesh.

curve only supported radius smoothing, add smooth for tilt and weight.

- add individual origin support for curves and improve the orientation calculations for curve handles,
- add support for using the active point's orientation.
- add support for creating new custom orientations from curves.
- fix error where only the last selected curve handle was taken into account for manipulator orientations.

sequencer: replace warning message with assert, was printing when copying masks and movieclips but went by unnoticed.

fix [#36262] Paste strip with video or sound content from another file crashes Blender

existing code was very stupid.

- all ID pointers for clipboard strips are handled uniformly.
- clipboard stores a duplicate ID pointer which are restored on paste.
- restoring pointers...
-- use ID's that are still in the database (copy&paste within the same file).
-- fallback to name lookup.
-- fallback to loading them from the original filepath (movie-clip and sound only).

also fix bug pasting where initialing the sound wasn't done if there was no frame-offset.

BGE Fix [#29575] Object not drawn in game engine

Implementing a GetBlenderImage for KX_BlenderMaterial so that modifiers draw correctly in multitexture mode. The preexisting limitation of 1 texture per material on objects with modifiers in multitexture mode still exists.

pasting strips in the sequencer didn't check if they overlap existing strips.

BGE fix [#21488] Pumpkin in Gamekit Tutorial flips upside down

A reference was being grabbed when a copy was wanted.

remove use_relative option from simple deform,
all modifiers should be using object transformations relatively.

fix [#36256] Checker Deselect, failed with de-selected active face.

avoid calling context functions when direct access is possible.

Fix [#36259] Select linked flat faces with Shift+Ctrl+Alt+F does not work in ver. 2.68

Code was cleaning BM_ELEM_TAG flag of verts, when it actually uses the one of faces...

Cycles / CMJ:
* path_rng_2D() was missing an else branch for the sobol case after fix in r57383.

* Compile fix for r58542, on Windows "subdir" was unknown.

correct own error in recent edits to editderivedmesh

use binary prefix for file sizes (old todo).
