There are three reasons why scrolling happens (first two cases of scrolling are actually due to
viewport transition that is triggered by annotation being traslated/created):
1. VisiblePageRect are NormalizedRect and should be represented by four values in [0, 1] interval.
Due to rounding errors caused by using QRect, they only reach the [0, 0.999] interval.
That means that right and bottom edge of the page are never visible so if annotation
is translated along the right/bottom edge viewport transition occurs (fixed in
PageView::slotRequestVisiblePixmaps)
2. For freehand line there are some constants (dX, dY) that make a line to be drawn outside
the page borders causing viewport transition. Removing these constants solves the problem (fixed
in SmoothPathEngine::event)
3. Browse mode is activated as soon as the cursor is moved outside the viewport.
Instead, we should forward the move event to the annotation which than can ignore the event (fixed
in PageView::mouseMoveEvent)
BUG: 436742
QLinkedList is deprecated in later Qt5 and gone in Qt6
The 1:1 port is std::list but in this cases all we ever do
is create the lists, push back to them, and pass then around
to be read, for that a QList is more than enough
Source files are no longer separated by UI and non-UI and similar,
but only by their build target.
* ui/ -> part/
* Move all source files from conf/ to part/
* Keep config skeleton definitions in conf/, needed for the mobile target too
* Move editdrawingtooldialogtest.h from conf/autotests/ to autotests/
* ui/data/icons/ -> icons/
* Move /part.cpp, /part.rc and similar files to part/
* Adapt include paths in source files
* Adapt CMakeLists.txt files (in / and in subdirectories)
* Adapt /Messages.sh
