-Add motion support from Simon Detheridge at the ember level instead of just individual xforms:
Add the ability to manipulate camera pitch, yaw and other goodies during flame rotation using a new element specified at the top-level of the flame.
Create a new 'saw' motion function, so that these values can effectively be looped (e.g. yaw -1 to +1) over the course of a rotation.
Add an offset to existing motion elements, to start them partway through their cycle. This would (for example) enable creating circular motion of xform affines, by combining two offset sine waves, one with an offset of 0.25 or 0.75.
Fix loops in EmberGenome (they only had an on/off effect - this was broken in flame-genome as well) and make the loop count floating-point as well. For sequence animations, it's not necessary for clips to loop precisely if they're not designed specifically for the ES project.
Similarly, there's no need for motion_frequency to be an integer value either so this was changed to allow motion that doesn't necessarily start or end at the loop boundary.
I've attempted to keep each bit of functionality in its own commit.
There's an argument as to whether to call the new flame motion elements <flame_motion/> (to differentiate programmatically) or just <motion/> (for consistency within the file) -- I opted for the former because it was easier to modify the xml parser that way.
--Code changes
-Change FlameMotion.h to EmberMotion.h to keep the naming convention consistent.
-Made elements of EmberMotion.m_MotionParams into their own type, MotionParam, which allows for CopyVec() to work.
-Change m_FlameMotionElements to m_EmberMotionElements in Ember.
-Use CopyVec() for EmberMotion instead of manual copy in copy constructors.
-Add exports in Ember.cpp for EmberMotion.
-Format eEmberMotionParam enum with one entry per line since it has many entries.
-Use fabs() in XmlToEmber instead of glm::abs.
-Minor formatting.
Allow for detaching of top level tabs in the dock widget so workspaces can be customized.
Save workspace between runs.
Only correct variation names/params during parsing when the source of the Xml file is not from Ember/Fractorium.

Slightly different grid/block logic when running DE filtering on the GPU.
Attempt a different way of doing DE, but #define out because it ended up not being faster.
Restructure some things to allow for a variable length xforms buffer to be passed to the GPU.
Add sub batch size and fuse count as ember members, and remove them from the renderer classes.
Remove m_LastPass from Renderer. It should have been removed with passes.

julia3d, julia3dz, loonie, mirror_x, mirror_y, mirror_z, rotate_x,
sinusoidal, spherical, spherical3d, stripes.
Unique filename on final render was completely broken.
Two severe OpenCL bugs. Random seeds were biased and fusing was being
reset too often leading to results that differ from the CPU.
Subtle, but sometimes severe bug in the setup of the xaos weights.
Use properly defined epsilon by getting the value from
std::numeric_limits, rather than hard coding 1e-6 or 1e-10.
Omit incorrect usage of epsilon everywhere. It should not be
automatically added to denominators. Rather, it should only be used if
the denominator is zero.
Force final render progress bars to 100 on completion. Sometimes they
didn't seem to make it there.
Make variation name and params comparisons be case insensitive.
--Code Changes
Make ForEach and FindIf wrappers around std::for_each and std::find_if.
