In Qt Quick (or in Qt Widgets when setting QT_NO_FT_CACHE to 1 or
when using OpenGL engine), the alphaRGBMapForGlyph() will be used
to get glyphs, because we need to keep our own cache. Transforms
was not supported in this code path, instead it was turned off
in supportsTransformations().

This patch enables transformations in the alphaRGBMapForGlyph()
and alphaMapForGlyph() code paths as well, since this is needed
for proper rendering with QT_DEVICE_PIXEL_RATIO.

Whenever the source model of a QSortFilterProxyModel changes, and
the changes involve the sorted column, the implementation removes
the changed rows from the mapping, sorts them, and inserts them back;
in case of identical items, the rows are inserted at the end of the
block of equal rows.

The problem is that if the change doesn't actually happen on the roles
that are used for sorting, then we shuffle the rows, terribly confusing
the user. The typical case is a model with identical checkable rows:
(un)checking one row will move it at the end.

So, instead of trying to be smart with the removal/sort/insert sorted,
simply resort everything under the changed parent index. Since the
sorting used is stable, this keeps the items in the same positions.

To ensure that the QGLWidget correctly releases the currently bound
framebuffer object when using a QPainter, we keep track of whether
QOpenGLFramebufferObject has modified the current FBO binding, and if
that's the case we need to read the OpenGL state directly instead of
relying on a cached value.

1. we build Qt with the latest sdk version, so the app needs

2. using a launch screen to support iphone6 depends on sdk 8
3. Apple requires apps that are pushed to appstore to use the
    latest version of the sdk.

Ideally we should store the sdk version used to build Qt, and
require that apps use the same version or newer. But this patch
will do until that is in place.
