* Scale icons returned by QIcon::fromTheme.David Sansome2012-10-101-2/+8
| | | | | | | | | | | | | | | | | The icon engine behind icons that are loaded from QIcon::fromTheme does not scale any pixmaps that it returns. When using an icon theme with an incomplete set of icons (for example, only a "128x128" folder), QIcon::pixmap will always return 128x128 pixmaps even if you ask for one of size 22x22. This is contrary to the QIcon::pixmap documentation that says "The pixmap might be smaller than requested, but never larger." This patch uses the same code that is in the main QIcon class in the PixmapEntry QIconLoaderEngineEntry to scale pixmaps if they are too big.

* Make the CPU detection much more efficient in user codeThiago Macieira2012-07-022-21/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.
