843be88e29 Manual High DPI test: Add a page logging all screen change signals to Metrics
Turn the Metrics widget into a QTabWidget and add a tab logging
all changed signals of QScreen.
This is useful when for example debugging issues with lock screens and
laptop hibernation.

43c8596be5 More polish of the manual High DPI test
The aim is to make it suitable to test for High DPI
bugs, ideally removing the need to provide bug report
examples.

- Add descriptive window titles/output
- Add options to force scaling on/off
- Change the updating of the text to be done in screenChanged()
  and log the signal.
- Rearrange the layout and show the descriptions as labels

7160df3a15 High-dpi drawTiledPixmap (raster paint engine)
Implement more consistent behavior for drawTiledPixmap(),
which should produce the same visual tiling pattern
independent of display devicePixelRatio

Consider the following pixmaps and draw calls:

  QPixmap px32; // 32x32
  QPixmap px64; // 64x64
  drawTiledPixmap(QRect(0, 0, 128, 128), px32);
  drawTiledPixmap(QRect(0, 0, 128, 128), px64);

On 1x displays this will produce 4x4 and 2x2 tiles,
respectively.

On 2x displays this would previously produce a different
tiling pattern, where the paint engine would tile in
the device pixel coordinate system. Change this to
tile in the device independent coordinate system,
producing the same visual tiling pattern as the 1x case.

It is possible to produce a 4x4 tiling pattern with
high-resolution output from the 64x64 pixmap by setting
the devicePixelRatio:

  QPixmap px64;
  px64.setDevicePixelRatio(2);
  drawTiledPixmap(QRect(0, 0, 128, 128), px64);

This change adds an inverse scale to the image filler
transform that accounts for the pixmap devicePixelRatio.

[ChangeLog][QtGui] QPainter::drawTiledPixmap() now
tiles in the device independent coordinate system.

83a5694dc2 Update copyright headers
Qt copyrights are now in The Qt Company, so we could update the source
code headers accordingly. In the same go we should also fix the links to
point to qt.io.

Outdated header.LGPL removed (use header.LGPL21 instead)

Old header.LGPL3 renamed to header.LGPL3-COMM to match actual licensing
combination. New header.LGPL-COMM taken in the use file which were
using old header.LGPL3 (src/plugins/platforms/android/extract.cpp)

Added new header.LGPL3 containing Commercial + LGPLv3 + GPLv2 license
combination

5e61bbe586 Basic high-dpi "retina" support for Qt 5.
Bring Qt 5 on par with Qt 4, prepare for more comprehensive
support later on.

Introduce device independent pixels (dips), device pixels,
and devicePixelRatio. Add high-dpi support to QPainter,
QGLWidget, the cocoa platform plugin, mac and fusion styles.

Dips are similar to CSS pixels, Apple points and
Android density-independent pixels. Device pixels
are pixels in the backing store/physical pixels on screen.
devicePixelRatio is the ratio between them, which is
1.0 on standard displays and 2.0 on "retina" displays.

New API:
QImage::devicePixelRatio() and setDevicePixelRatio()
QPixmap::devicePixelRatio() and setDevicePixelRatio()
QWindow::devicePixelRatio()
QScreen::devicePixelRatio()
QGuiApplicaiton::devicePixelRatio()
