We have a missleading function QTextCursor::columnNumber() since 4.2,
which almost never returns what you want.
The pattern cursor.position() - cursor.block().position() is used
frequently in code using QTextCursor.

When the paint engine does not support QStaticText, we fall back to
regular drawText() calls. This fallback would previously paint all
text to (0, 0). This fixes the qstatictext autotest on Linux.

isEmpty() function in QStaticText
To make the return value of text() more intuitively clearer, and to make
the API more readable, I've separated out the text format into a
separate property. The isEmpty() function seemed out-of-place in the
API, as suggested by reviews, so it has been removed.

QStaticText was previously made private API to support inclusion in
Qt 4.6.x. This change turns it back into public API for Qt 4.7.0.

We can't add new symbols to QPainter for Qt 4.6.x, as we would not be
able to remove them again if we regretted the API. Hence, I've made
removable symbols instead, a private global function and a
drawStaticText() in QPainterPrivate. In order to tie things together,
I needed a static private-getter in QPainterPrivate, and hence it
had to be a friend of QPainter.

Some changes were made to QTextEngine for the sake of QStaticText,
but as the implementation of QStaticText changed, these are no longer
needed. Although they are harmless, I'll remove them to minimize the

Turns QStaticText into private API in preparation for Qt 4.6.x. The
related functions in QPainter are marked as internal in the docs. There
are already internal functions in QPainter, so this seemed like a
reasonable solution. Since the functions require QStaticText they will
not be accessible to anyone who does not include private API.

There's a big improvement to be seen in the OpenGL engine by caching
the vertex data for the QStaticText in VBOs. In order to have the
buffers properly disposed, I've implemented a userdata concept for
QStaticTextItem. By default, the optimizations will be turned off, and
can be turned on by using the useBackendOptimizations flag.

The two runs (counting the number of items and then storing the
information) needs to be identical, so they need to have the same text
flags set. Otherwise we would count more items than we actually
generated and crash later when we tried to access an uninitialized
item.

I've added a flag char, so the size of the static text is now one byte

In order to be feature consistent with drawText(), we have to clip the
text whenever the text expands beyond its borders. This is a
performance hit, but luckily we can detect the cases where it's
necessary before-hand.

Allow the QStaticText layout to be completely defined prior to painting

The OpenGL and OpenGL2 engines now have support for static text, as
well as the QEmulationPaintEngine.
Also contains an optimization: Instead of passing both the position and
glyph positions to drawStaticTextItem() we add the position into the
glyph position and update it only when it changes. Otherwise we would
have to do this work in all engines for every call. This means we have
to cache the position in QStaticTextPrivate as well, but it seems like
a small price to pay, since it's a per-text overhead and only 16 bytes.

painter
1. The font property in QStaticText has been removed. Rather than set a
font on the text explicitly, it picks up the font from the painter. If
you change the font on the painter, the text layout will have to be
updated, like with a matrix.
2. The translation might not be the only transformation on the painter,
so rather than translate back to origo, we explicitly set dx and dy
on the transform to 0.0 for the duration of the function.
3. Update test to reflect changes

the matrix do it when calculating the positions inside
getGlyphPositions().

1. Support transformations on the painter in drawStaticText().
Transforming the painter will cause the text layout to be recalculated,
except for translations, which are handled by shifting the position of
the text items.
2. Make const length arrays of the internal data in QStaticTextItem in
order to minimize the memory consumption.

By caching the results of getGlyphPositions() we can make a code path
in the critical paint engines which is optimal both in space and speed.
The engines where speed is of less importance (pdf engine etc.) which
may need more information, we choose the slower code path of drawText()
which lays out the text again. We should have optimal paths in raster,
vg and GL2 paint engines. The others are less important. Memory
consumption of static text is now 14 bytes per glyph, 8 bytes per item
and a static overhead of 40 bytes per QStaticText object.
