Currently QOpenGLTextureCache::bindTexture always convert any uploaded image to RGBA8888 before uploading. This is quite inefficient when OpenGL natively supports uploading formats in the original format. This patch adds support for uploading a few native QImage formats. This also get the performance of QOpenGLTextureCache::bindTexture on par with QGLContext::bindTexture. The texture brush used by QOpenGLPaintEngine is also converted to QImage, since bindTexture will convert it to QImage anyway, and going over QPixmap may cause an unnecessary conversion. [ChangeLog][QtGui][QOpenGLTextureCache] Support uploading common QImage formats directly to OpenGL when supported.

This directory contains autotests and benchmarks based on Qt Test. In order
to run the autotests reliably, you need to configure a desktop to match the
test environment that these tests are written for.
Linux X11:
* The user must be logged in to an active desktop; you can't run the
autotests without a valid DISPLAY that allows X11 connections.
* The tests are run against a KDE3 or KDE4 desktop.
* Window manager uses "click to focus", and not "focus follows mouse". Many
tests move the mouse cursor around and expect this to not affect focus
and activation.
* Disable "click to activate", i.e., when a window is opened, the window
manager should automatically activate it (give it input focus) and not
wait for the user to click the window.
