Vc is already disabled by default and does support
amd64, which will not match the current condition.
This check only has an effect when all=ON is passed
to CMake, and in this case we ought to respect what
was requested on the command line as well.

FTGL is only needed when building ROOT with support for
OpenGL, which is not the case when -Dminimal=ON is used.

In ROOT, CMAKE_CXX_STANDARD is always defined. However,
on dependent projects that use this function we need to
check, since CMAKE_CXX_STANDARD may not be defined.

fPool should be used in Form() when it's not null,
not the reverse.

Main problem - correct cleanup of WebGL context.
Without it very soon browser remove old drawing - means geometry
disappers

Plus fix small errors in hover event handling

By default all binary buffers for shapes created on the server,
but JSROOT able to create same data from TGeoShape. 

Binary size of cylindrical shapes can be large.
Provide a feature (not yet enabled) to transport TGeoShape to client and
build 3D object there. Let investigate performance and drawbacks

It is packed inside JSON - as compressed array.

It will contain different information on the node
Idea to avoid context menu as was used before but react on the click
events in the TreeTable

ui5 sometime fully recreate DOM elements, therefore one has to
re-assign Canvas object to the new DOM afterwards.
Requires special functionality, which should be moved later into JSROOT

It provides two areas, which at the best fit to the needs.
Later one can implement many different details pages to show nodes
information or special drawings

fix memory leak when fitting histograms using linear fitter and functions built from expression using special operator ++. This fixes ROOT-10147

* Replace snprintf by TString::Format in THistPainter

* change the way "ef" is returned

* Better version

HistFactory normally collects histograms automatically, but not if
`HistoToWorkspaceFactoryFast::MakeSingleChannelWorkspace` is used.
This commit fixes this defect, and adds sanity checks.

ROOT-10162

This patch moves code which does similar things into standalone routines. This
way we make more clear the intent of use.

We do not need forward declarations and payload code if we have a module.

Factories in RooFit are often handled using global static pointers
that are initialised and deleted manually.
Making these function-local statics makes this process automatic.

- This was done for NumGen(Config|Factory), NumInt(Config|Factory),
RooMsgService, RooNameReg, ExpensiveObjectCache, RooRealConstant,
RooResolutionModel
- It further required breaking a cyclical dependency when constructing RooNumIntFactory.
- Finally also fix doxygen for RooResolutionModel
