OCCT 7.3 did not work well when using a very large projection plane, so
this commit reduces the plane size to the minimum required for the cut
operation. It also performs some minor refactoring in anticipation of
the implementation of the true projection feature, and it removes the
last attempted fix, which proved unnecessary.
This ensures the rotation edge and mode GUI elements are cleared when starting
to add or edit a component. Previously, when adding a new component or
editing one without rotation, the GUI elements would retain the value
from the previously edited component, which made it hard to check that
components did not have any rotation, and would make it easy to
accidentally add rotation to components that did not need it (just by
clicking edit and confirming).
Address a hang when using older versions of OCC to create a rotated
extrusion. This approximates the auxilliary spine as set of line
segments formed from the helix, rather than using the helix directly.
SO's auto rotation has its own rotation logic that ends at fixed positions. This collides with the "to nearest" option whose aim is to rotate to the next sensible state taking into account from what position the rotation was started.
Thus the solution is to disable SO's auto rotation while the cube is rotated.
fixes bug 4495
- add missing edge faces
- implement a proper rotation recipe -> rotate towards the nearest possible state
- add preferences settings to turn off this new rotation behavior
- get rid of transparent cube faces to avoid wrong clicks, this way also remove the backfaces
- to make the edge faces fit, use triangles for the corners
- expose cube size setting to preferences dialog
- add new button to view backside
- get rid of bitmaps because as reported in https://forum.freecadweb.org/viewtopic.php?f=3&t=52118&start=20#p481781
the x y z labels are not scaled on HiDPI screens
moreover they are often "in they way" when you want to click on a corner and in principle they don't provide more info since we already have the CS with the axis labels
- also fix an arithmetic overflow compiler warning
- also rename 2 variables

The fix:
Setting the render type to Image causes the issue, but neither do I know why it is
necessary to set it to Image, nor do I understand why this is causing the issue. I
only know it solves the issue.
By default (on platforms that support it, X11 and Windows currently) QT
applies compression for high frequency events (mouse move, touch, window
resizes) to keep things smooth even when handling the event takes a
while (e.g. to calculate snapping).
However, tablet pen move events (and mouse move events synthesised from
those, which is what FreeCAD uses) are not compressed by default (to
allow maximum precision when e.g. hand-drawing curves), leading to
unacceptable slowdowns using a tablet pen.
This commit enable compression for tablet events here to solve that and
make use of a tablet just as smooth as a mouse with FreeCAD.
This can (and likely will) lead to some movement events being dropped,
but since there is no freeform curve drawing tool, that should not be
problematic (and if it is ever added, it could still work without
compression if the mouse movement event handler is written to be fast
enough).
Qt has deprecated the following constants, this commit replaces them
with their new equivalent/replacement:
Qt::TextColorRole -> Qt::ForegroundRole
Qt::BackgroundColorRole -> Qt::BackgroundRole
QPainter::HighQualityAntialiasing -> QPainter::Antialiasing
QPalette::Foreground -> QPalette::WindowText
Removes old Qt code, restores the conditional inclusion of the
3Dconnexion license information, shortens the displayed hash, and links
the hash to its repo.
