Our GUI code uses a mix of floats and doubles to represent floating
point numbers, and in a few places interchanges them in a way that
causes an invisible loss of precision. Change the double precision
"default" values to float defaults, and use the appropriate value for
pi.
* renamed SoFCCSysDragger to SoTransformDragger
* moved TDragger, RDragger and TPlanarDragger to separate files and also renamed them to be more descriptive
This adds optional origin indicator ofr SoFCPlacementIndicator. This is
something that can be used to clearly indicate origin placement with
small sphere.
This adds SoFCPlacementIndicatorKit - a node that can be used to
show position of object to the user. It can be configured in various
ways so it should be a good base for future unification of features like
this across the application.
Every basic data type is stored in Base module, color is standing out as
one that does not. Moving it to Base opens possibilities to integrate it
better with the rest of FreeCAD.
* On lines where the variable type is obvious from inspection, avoid repeating the type using auto.
* When possible use a ranged for loop instead of begin() and end() iterators
* Add always zoom invariant and always on top rendering to
ViewProviderDatumCS
* Add a new utility class AxisOrigin for more efficient axis rendering.
Also exposed to python.
* Change ViewProviderPlacement to use AxisOrigin for rendering.
A single instance of AxisOrigin is shared by all
ViewProviderPlacement. Selection context is used to distinguish among
different instances.
Before that (e.g. on MacBook Pro) it was very hard to see the microscopic selection-circle hidden behind much bigger cursor arrow when trying to snap e.g. a line to some vertex. Now this setting can be used for such displays to increase the marker size and make it clearly visible behind the cursor.
The already existing "sketcher marker size" property is intended to be used for sketcher only, so it's not suitable for global setup of all the markers' sizes uniformly...
