Add Curves member to Ember.
Add curves capability to EmberCL.
Remove some unused variables in the kernel created in RendererCL::CreateFinalAccumKernelString().
Use glm namespace for vec classes if GLM_VERSION >= 96, else use glm::detail.
As a result of using glm namespace, all instances of min and max had to be qualified with std::

Add the ability to save ember Xmls to an unique automatically generated name after the first time the user has specified a name.
--User changes
Use actual strips count when computing memory requirements in the final render dialog.
Output CL_DEVICE_ADDRESS_BITS when passing --openclinfo to command line programs.
Warn if single/total allocations are greater than the max allowed for OpenCL in the final render dialog.
Make about box properly sized for different fonts.

Major work to get it running on Linux.
Migrate from QGLWidget to QOpenGLWidget.
Delayed init due to QOpenGLWidget.
Break RendererBase::MemoryRequired() into two functions, it and HistMemRequired() and return a tuple.
Add GlobalMemSize() and MaxAllocSize() functions in OpenCLWrapper.
Change CHOOSE_XFORM_GRAIN to be 16384, so we can & with 16383 instead of using modulo when selecting an xform. This results in a 9% speed increase on the CPU.
Save each newly loaded ember in a file called "last.flame" in the executable folder. This will help diagnose crashes that occur when switching embers.
Use nullptr instead of NULL in the Fractorium project. It had previously been done in all other places.
Make EmberRender and EmberAnimate place their output renders in the same folder of the input parameter file. Previously it was just placing them in the same folder as the executable, which is wrong.
--User Changes
Size is no longer fixed to the window size.
Size scaling is done differently in the final render dialog. This fixes several bugs.
Remove Xml saving size from settings and options dialog, it no longer applies.
Final render can be broken into strips.
Set default save path to the desktop if none is found in the settings file.
Set default output size to 1920x1080 if none is found in the settings file.
--Bug Fixes
Better memory size reporting in final render dialog.
--Code Changes
Migrate to C++11, Qt 5.3.1, and Visual Studio 2013.
Change most instances of unsigned int to size_t, and int to intmax_t.
Add m_OrigPixPerUnit and m_ScaleType to Ember for scaling purposes.
Replace some sprintf_s() calls in XmlToEmber with ostringstream.
Move more non-templated members into RendererBase.
Add CopyVec() overload that takes a per element function pointer.
Add vector Memset().
Replace '&' with '+' instead of "&" in XmlToEmber for much faster parsing.
Break strips rendering out into EmberCommon and call from EmberRender and Fractorium.
Make AddAndWriteBuffer() just call WriteBuffer().
Make AddAndWriteImage() delete the existing image first before replacing it.
Add SetOutputTexture() to RendererCL to support making new textures in response to resize events.
Remove multiple return statements in RendererCL, and replace with a bool that tracks results.
Add ToDouble(), MakeEnd(), ToString() and Exists() wrappers in Fractorium.
Add Size() wrapper in EmberFile.
Make QString function arguments const QString&, and string with const string&.
Make ShowCritical() wrapper for invoking a message box from another thread.
Add combo box to TwoButtonWidget and rename.
0.4.0.9 Beta 07/27/2014
--User Changes
Properly set tab order on all controls.
Calculate and report iters/second in the final render dialog.
Immediately draw yellow dot on xform mouse down on previously unselected
xform.
--Bug Fixes
Fix GlynnSim1, GlynnSim2, GlynnSim3 and juliaNab by ensuring the first
argument to pow() is >= 0.
Ensure OpenCL platform and device combo boxes in the final render dialog
expand as needed.
--Code Changes
Make VariationTreeSpinbox take its parent VariationTreeWidgetItem as a
constructor argument. This makes SetupVariationTree() and
VariationSpinBoxValueChanged() more efficient.
Make Interference2 and ho use fabs().
0.4.0.7 Beta 07/26/2014
--User Changes
Color code xforms like Apo does.
Change other aspects of xform color drawing.
Add option to invert the Y axis to both the options final render
dialogs.
Coordinate Y axis setting with preview renders.
Add option to show all xforms when dragging. Previously, only the
current one was shown.
Make final render dialog appear in the middle of the screen.
Immediately draw yellow selection dot on mouse down.
--Bug Fixes
Resize final render dialog vertically if it's taller than the 90% of the
desktop area.
0.4.0.5 Beta 07/18/2014
--User Changes
Allow for vibrancy values > 1.
Add flatten and unflatten menu items.
Automatically flatten like Apophysis does.
Add plugin and new_linear tags to Xml to be compatible with Apophysis.
--Bug Fixes
Fix blur, blur3d, bubble, cropn, cross, curl, curl3d, epispiral, ho,
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.
