- Replace Nokia contact email address with Qt Project website.
- Remove "All rights reserved" line from license headers.
As in the past, to avoid rewriting various autotests that contain
line-number information, an extra blank line has been inserted at the
end of the license text to ensure that this commit does not change the
total number of lines in the license header.

Simple search and replace. This commit doesn't touch 3rd-party files,
nor translations (where the change is not so simple and will be handled
in a separate commit).

To avoid calling the bounding box function for the same non-printable
characters in every call, we cache them as empty in the coords table
and bail out before painting them. This patch also fixes some possible
reads of uninitialized memory (reference to return value) and reference
to a default constructed object consisting of uninitialized pods.

Two possible failures when using the glyph cache on raster engine and
populating the cache with very many glyphs:
1. Change 72f161739b270b01807f97cd853030440f0fd430 caused the maximum
height of the glyph cache to be 32768, which was not sufficient for
large fonts with very many characters (e.g. Chinese text)
2. Since we are using QPainter to draw into the glyph cache for RGB32
glyphcaches, and QPainter does not support very high coordinates,
we need to create a reference image that references a section of the
glyph cache and paint into that instead.

When the OpenGL glyph cache filled up (the max texture size on the
hardware was exceeded) the characters would be drawn as black blocks
instead. As a work-around for this, the cache will now be cleared and
repopulated whenever this happens, meaning that once in a while (when
a lot of different glyphs have been drawn in a font) there will be a
performance hit. A more complete solution is described in QTBUG-13784,
but this requires so much refactoring that it was deemed too risky for
a patch release. This patch fixes the problem with a small penalty
and low risk.

Our glyph caching system doesn't take GL texture size limitation into
account, and assumes you can create an infinitely large texture.
On top of that, the cache will never create a cache that is wider
than 256, or QT_DEFAULT_TEXTURE_GLYPH_CACHE_WIDTH, which means we'll
hit the texture size limit even faster. With this patch the entire
texture is utilized. However, to fix in properly we need to support
having multiple texture for each font engine. That will be fixed
shortly (see task QTBUG-13784).

For the raster engine to provide the same quality of text rendering
as the native engine on Mac Cocoa, we need to support rendering to
different sub pixel positions for each glyph. The number of
subpixel positions is arbitrary and has to be detected, but it's
usually three or four.
Each position will give slightly different coverages inside the
pixel and thus different rasterizations. Other font engines which
support sub pixel positioning of glyphs can provide the same
functionality by implementing supportsSubPixelPositions() to return
true, and then adding the subPixelPosition argument to the x
coordinate used in alphaRGBMapForGlyph().

Separate getting the glyph coordinates from actually making and
populating the cache. Calling populate() and fillInPendingGlyphs()
immediately after should be equivalent to the old code, except it might
have fewer reallocations of the texture since you will only create it
one per set of glyphs.
This mainly enables populating the GL glyph cache outside a GL context
and then actually drawing into it later, when the context has actually
been established.

The driver in the N900 doesn't support glCopyTexSubImage
or glReadPixels for FBO's that have a GL_ALPHA or POT
color attachment. The ifdef'ed code in resize() was
a previous attempt to make this work which didn't.
We could have changed the texture to be GL_RGBA and changed
the texture size to be NPOT, but that would have wasted
precious GPU memory and would have been slower, so we
waste a bit of system memory instead, by having a QImage
copy along with the texture.

Since the paint engine now transforms the prerendered glyphs instead of
rendering transformed glyphs as paths, we need to turn on texture
filtering to avoid antialiasing artifacts. In order to do this, we also
need to pad the glyphs in the glyph cache, otherwise you will get
artifacts when sampling the area around the glyph's bounding rect (where
there might be other glyphs.) This done by adding a glyphPadding()
function to the cache which returns the number of pixels to pad between
each glyph.

The height of the row is not only decided by the maximum height of the
set of glyphs currently being added to the glyph cache, but also the
height of the glyphs previously added to the current line in the glyph
cache. To minimize the space used, we now calculate the maximum height
for glyphs per line, and use this as the vertical advancement when
positioning the next line in the cache. The change also removes a
redundant test ((c_x + c.w > c.h) is caught earlier on and will
always be false at this point.)

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.

This makes Qt work on VxWorks 6.6+ in native (kernel) mode.
* compiles with the WindRiver GNU toolchain (Linux only)
* works with QWS (tested with the VNC driver only)
* tested on PPC hardware and the x86 VxWorks simulator
* no q3support, no phonon, no webkit
* no QSharedMemory, no QSystemSemaphore, no QProcess
* only one QApplication instance (flat address space)
* filesystem support depends heavily on the quality of the native driver
* QLibrary is just a dummy to make plugins work at all
* qmake transparently creates VxWorks munching rules for static ctors
* made auto-test cope with missing OS features
A special note regarding the Q_FOREACH patch for dcc:
when calling foreach(a,c) with c being a function returning a container,
the compiler would generate 5 references to some labels (.LXXXX), which
are not there (so the linker complains in the end).
Seems like dcc doesn't really like the 'true ? 0 : <function call to get type>'
statement
