-Numbering of rendered files was wrong.
-Truchet_hex_fill was not compiling with some newer Nvidia drivers.
--Code changes
-Update Wix installer to use VS 2019.
Revert file path construction behavior to not strip forward slashes from prefix so it can be utilized to change output directory

--User changes
-Allow users to set the Exp value when using the Exp temporal filter type.
-Set the default temporal filter type to be Box, which does not alter the palette values at all during animation. This is done to avoid confusion when using Gaussian or Exp which can produce darkened images.
--Bug fixes
-Sending a sequence to the final render dialog when the keyframes had non zero rotate and center Y values would produce off center animations when rendered.
-Temporal filters were being unnecessarily recreated many times when rendering or generating sequences.
-Exp filter was always treated like a Box filter.
--Code changes
-Add a new member function SaveCurrentAsXml(QString filename = "") to the controllers which is only used for testing.
-Modernize some C++ code.
-Allow for specifying linear or smooth interpolation when generating a sequence in the Library tab (was formerly hardcoded to smooth). This has the effect of exposing the --unsmoother option used in EmberGenome in the GUI.
-Clarify tool tips of the sequence interpolation fields in the animation group on the Flame tab.
-Change caption of the Bounds tab to be Bounds & Log.
-Fix improper usage of rand() in cpow2, cpow3, hypertile1, hypertile3D1, hypertile3D2, juliac, juliaq.
-Fix program crashing during density filtering on some Nvidia cards.
-hypertile3D1 was wrong.
-Parsing phoenix_julia when coming from Apophysis was wrong.
-Density filtering was freezing on certain Nvidia cards.
--Code changes
-Optimize juliac, npolar.
-Add a new function Crand() which behaves like the legacy C rand() which returns an integer between 0 and 32766, inclusive.
-Use RandBit() in some places.
-Remove Zeps() from vignette, it's not needed.
-Restructure OpenCL code for density filtering such that it does not hang after being compiled on some Nvidia cards, such as the gtx 1660. Remove barriers from conditionals where possible.
-Add support for Chaotica files which specify xform weight as "Base weight" instead of "base_weight".
-Fix bug where Fractorium would crash when a new file was dragged in while previews were still rendering.
--This was done by changing the TreeItemChanged() events in the library tab use a direct connection rather than a queued connection.
--This obviated the need for QCoreApplication::processEvents() calls in the library tree code.
-Fix bug where renaming a flame within a file, then tabbing away did not commit the name change.
--Code changes
-Clean up some warnings about const variables in the latest version of Visual Studio 2019.
-Upgrade installer to latest update of Visual Studio 2019.
