Revert to the pre highdpi-patch behaviour.
Before, both physical and logical DPI would be based
on the dpmx/dpmy variables, which could be changed
with setDotsPerMeter(). The highdpi patch introduced
separate ldpmx/ldpmy variables, which were not
changed by setDotsPerMeter().
This broke when loading images: setDotsPerMeter
would be called but the logical dpi would not change.
Remove ldpmx/ldpmy. Keep scaling the physical dpi
by the devicePixelRatio, which will be set to 1 by
default.

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()

First, check that the option in question hasn't been already enabled
by the compiler, via compiler switches. If it has been, then we don't
need to verify anything, and we can assume that it's safe to use such
instructions. For example, on an x86-64 build, qCpuHasFeature(SSE2) is
always a constant true.
If the compile-time check fails, then we proceed to try and detect the
processor features at runtime. But instead of insisting on a call to
qDetectCPUFeatures, allow the code using the detection to read from a
variable and simply test it for values. Only if the variable isn't
initialised should it make a function call. The Q_ASSUME allows this
code to be very efficient even with multiple uses of qCpuHasFeature.
Change the uninitialised value from -1 to 0 so that simpler
instructions can be used to check for non-initialisation.
The qDetectCPUFeatures function is renamed to qDetectCpuFeatures to
match the Qt coding style and also to catch uses this code that need
to be adapted.

The QT_HAVE_xxx macros are replaced with QT_COMPILER_SUPPORTS_xxx.
They indicate that the compiler supports those intrinsics, but not
necessarily that they can be used right now.
ICC and MSVC allow one to use the intrinsics anywhere, but for Qt all
uses of the intrinsics are either in specially-built files, protected
by runtime checks, or they are unconditional (qstring.cpp). So we only
use the intrinsics when the compiler was instructed to generate code
for that instruction set anyway.

The main reasons for doing this are:
1. _qpa.h end up in the master QtGui include file. QtGui is meant for
userland applications. qpa code is neither binary nor source compatible.
Inadvertant use of QPA api makes the user code binary-incompatible.
2. syncqt creates forwarding headers for non-private header files. This
gives people the impression that this is public API.
As discussed on the mailing list, even though QPA api is internal and subject
to change, it needs to treated differently from private headers since they
will be used by in-qtbase and out-of-qtbase plugins.
This commit does the following:
1. The _qpa in QPA header files is dropped.
2. syncqt now treats any file with qplatform prefix as a special file and
moves it to qpa/ directory. The recommended way of using QPA API in plugins
is: #include <qpa/qplatformfoo.h>. This allows the user include QPA API
from multiple modules (for example, qplatformfoo might be in QtPrintSupport)
3. The user needs to explicitly add QT += <module>-private to get access to
the qpa api.
4. Creates compat headers for the olden style qplatformfoo_qpa.h and QPlatformFoo
includes.
This commit does not change the cpp filenames. This requires a more careful
merging of existing non qpa cpp files and existing cpp files on a case by
case basis. This can be done at anytime.
The following files are not renamed as part of this changed but will be fixed
as part of a future change:
src/gui/kernel/qgenericpluginfactory_qpa.h
src/gui/kernel/qgenericplugin_qpa.h
src/gui/kernel/qwindowsysteminterface_qpa.h
files were renamed using
for x in `find . -name "qplatform*_qpa.h"`; do git mv $x "${x/_qpa.h/.h}"; done
for x in `find . -name "qplatform*_qpa_p.h"`; do git mv $x "${x/_qpa_p.h/_p.h}"; done
includes were renamed using script
for file in `find . -name "*.h" -or -name "*.cpp" -or -name "*.mm"`; do

Frameworks like CoreGraphics or Cairo offer a similar method of

This patch adds this functionality to QImage by extending the
QImage constructors that take a raw image buffer pointer.

Since FreeType has internal caching, it has had a special
code path in the raster engine which avoided using Qt's glyph
cache, as that would be redundant. However, when compiling
with QPA, we want the same behavior without being able to
access the QFontEngineFT class. To achieve this, I've made
a new abstraction and added it to QFontEngine which allows
the FT engine to provide direct pointers into the alpha maps
stored by FT. This requires a locking/unlocking mechanism.
Yes, the QFontEngine::alphaMap* API is slowly becoming a horrible
mess, but due to time constraints, the task of refactoring these
functions into a more flexible API needs to wait. I've added a
TODO comment for this.
