Needed to make the blender link libraries a global property
now that tests are parallel to source directory.
Current sort order for blender link libraries doesn't work
for tests that start with few defined symbols. Doubling the
lib list works, but a TODO to find a better way (probably
using CMake's own mechanism for tracking dependencies).
** TO BE PORTED BACK TO 2.71 **
As pointed out by Thomas Beck (plasmasolutions), the current behaviour and/or
default values for their parameters didn't quite make sense:
1) Back Easing - The old default value of 0.0 results in some overshoot being applied,
while trying to tweak it up or down resulted in some odd jumps and discontinities.
I've ended up removing some code here which forcibly using a "back" value of 1.7
when users wanted 0.0 instead. There doesn't seem to be any good reason for this.
To ensure that there is still an effect initially, keyframes now get created
with back set to 1.7
2) Elastic Easing - The old default settings of <amplitude = 0, period = 0> resulted
in a curve without any elastic bounce, which wasn't very useful for motion graphics.
Now, default values of amplitude = 0.8 and period = 4.1 get set. These were hand picked
by Thomas to work well when the duration of the motion is 10 frames long (i.e. the
typical length of such effects when doing motion graphics).
Issue here is that if there's a texture in the tree, chances are it has
already been set as active texture so groups are never traversed.
Now changed logic so that if a group node is active, its own active
texture takes priority over the parent group active texture.
Cleanest way here is not do bounding box collision for editmeshes at
all. Decision is taken because:
* Usually we want to do the snapping to the edited mesh anyway (when we
don't the mesh is skipped completely, so we don't need to worry for
extra checks)
* Bounding box is calculated from derived mesh. This means that for
subsurfed meshes for instance, the bounding box may be significantly
smaller than the size of the edit mesh.
Looks like the cleanest way to handle this is to no do bounding box collision
for edit mode at all. But this is easy to enforce
This reverts commit 7b5fe4f316.
