Sometimes Open Sans Semibold fails to load properly on the latest
Windows Creators Update. In that case try to load Segoe UI instead.
An attempt to fix#3276.
Now group of Ui::Radiobutton instances share Ui::RadiobuttonGroup.
All value management is done through the group instance, not through
separate radio buttons. Also a template for groups over enums added.
Currently the build without implicitly included precompiled header
is not supported anyway (because Qt MOC source files do not include
stdafx.h, they include plain headers).
So when we decide to support building without implicitly included
precompiled headers we'll have to fix all the headers anyway.
Sometimes Text::_maxWidth was not accumulated correctly because
the intermediate text blocks had negative right bearing larger
than the whole width of the next text block, so the final computed
line width was less than some intermediate value. Now we accumulate
the _maxWidth value after each block making this value correct.
Some major platform-dependent file operations refactoring.
All methods like "open file", "open file with", "show in folder"
were moved to core/file_utilities module with platform-dependent
backends. All methods interacting with DesktopServices made async.
Now each platform-dependent module declares its interface in
platform/platform_module.h file and after that includes platform-
specific headers like platform/win/module_win.h with implementation.
Also removed the legacy WinRT platform-dependent implementations.
Commit 8d354382a4 introduced a regression in RTL phrases display.
When an RTL line had trailing spaces we started displaying them in
front of the text still assuming counted line width value that did
not include those trailing spaces.
Line width is not including trailing spaces width because it is
allowed to fit in the line any number of spaces.
Also text block "left padding" entity was eliminated. If we have
some spaces in the start of the text block (for example a text block
after a link) we just add an empty word and mark those spaces as its
right padding.
Now base::lambda can be copied and can wrap any immutable lambda.
For mutable lambdas there is base::lambda_once (which you're
supposed to call only once to pass data through lambda captures,
for example by using std::unique_ptr). Generally base::lambda is
passed by value and base::lambda_once is passed by rvalue reference.
If we start logging in and we know, that some of the authorization
keys were read from the hard drive, not generated, we destroy all
the existing authorization keys and start generating new keys.
