Fixed panning bug, when using RUN_ON_DEMAND, that resulted in the camera being thrown off towards infinity.  

The solution for to refactor the way that events are checked so I add a bool return type to checkEvents() method across osgViewer::GraphcisWindow, osgGA::Devive and osgViewer::Viewer/CompositeViewer classes
Removed redudent code
From Jordi Torres, "We must use JNI_FALSE instead of false in JNI code. Otherwise the examples will not compile. This patch should be applied to osgAndroidExampleGLES1/jni and osgAndroidExampleGLES2/jni. the osgNativeLib.cpp is the same. "
Resrtuctured the use of static's in the Uniform::getNameID() method to avoid problems under Android.
From Farshid Lashkari, " small update to TangentSpaceGenerator to support QUAD_STRIP primitive types."
Updated ChangeLog
Updated AUTHORS file
Moved quad buffer definitions into include/osg/Camera
From Martin Naylor, "I am receiving 1 build error whilst building the SVN, its in osgforest as follows:

error C2065: 'GL_RGBA32F' : undeclared identifier

Shoudlnt that be GL_RGBA32F_ARB as defined in texture header?

Attached is the easy fix :)."

Added an OSG_INIT_SINGLETON_PROXY(..) to initialize the static s_GLExtensionDisableString variable
Fixed View::setUpViewInWindow() parameter
Fixed the computation of the spot light direction.
From Diane Delallée and Sukender, "1. Image.cpp
Failure to perform a vertical flip on S3TC-DXTC now simply leaves the original image instead of corrupting it.
Image.cpp was sometimes performing a "normal" (= for uncompressed images) vertical flip on S3TC-DXTC images, producing weird results.
Actually, code was trying a "DXTC vertical flip" and relied on the result to call a "normal vertical flip". But when the "DXTC v-flip" encounters an error, this is is not necessarily because the image is not S3TC (ex: unhandled image dimensions)!
So now the code simply does "if dxtc, then flip_dxtc; else flip_normal;".

Note from Robert Osfield, moved the isDXT function into the dxt_tool file and namespace.
From Diane Delallée & Sukender, "Added some support of non-modulus-4 dimensions in S3TC-DXTC images (previous implementation seem just not to handle these properly).
- Added missing packing value on S3TC images. Images are coded with 4x4 blocs, whatever the image size. So there is an horizontal packing of 4 pixels (2 bytes in DXT1, 4 bytes in DXT2-5).
- Added crash guard against writing corrupted S3TC images.
Notes:
- What is missing is a support of "lines packing" in osg::Image (see code comments).
- S3TC-DXTC vertical flipping crashes (access violation) with some unusual dimensions (see code). I could not implement missing cases, so I added guards to avoid crashing."
From Sukender, "Added vertical flipping to the writer depending on the Image::getOrigin() value (= flip the image when Image::BOTTOM_LEFT). Most of the time this will not change DDS writing (= no v-flip), as it seems images are rarely "BOTTOM_LEFT". To skip this behaviour, the "ddsNoAutoFlipWrite" option was added.
I also moved a few lines of code about "dds_flip" option, and made options reading more like in other ReaderWriters."
From Sukender, "Added ".dds" file deletion on writing failure."
From Marcin Prus and Robert Osfield, moved the key parts of the .dds plugins computeRowWidthInBytes implementation into the osg::Image::computeImageSizeInBytes(..) to
address bugs in the computation of image size.
