(KTX). The KTX file format is straightforward and designed to be easy to
use in OpenGL.

The attached plugin can read:
* 1D, 2D, and 3D textures
* uncompressed and compressed images
* mipmapped and non-mipmapped textures
* little-endian and big-endian files
* textures from files as well as seekable istream objects
It does not handle:
* array textures (not supported by the ReaderWriter API)
* cubemap textures (not supported by the ReaderWriter API)
* the "KTXorientation" key-value pair; support could be added later (see
the file format spec for more information)
* non-seekable istream objects (would require more complicated memory
management)

What happens is this:
A view is created, and then the viewers thread is created and runs.
The setReleaseContextAtEndOfFrameHint is true.
To create a second view, the viewer is setDone(true), and we wait for the thread exit.
At this point, inside the ViewerBase::RenderingTraversals code, there are places where it reads "if(_done) return;"
The problem, is that it won't reach the code that will releaseContext().
Apparently, this driver won't let any other thread to makeCurrent(), if another thread (dead or not) has ownership. So when the Viewers is re-started, the first view won't be able to use the gc.
The change attached (against rev 13153) corrects this."
Attached are changes to GraphicsWindowIOS.mm to support setting up the new buffer type when compiling for iOS5,
also attached is a small change to FrameBufferObject.cpp to report support for packed depth stencil via the
GL_OES_packed_depth_stencil extension.
For anyone reading this you can attach a packed depth stencil to your FBO like so
_rttCamera->attach( osg::Camera::PACKED_DEPTH_STENCIL_BUFFER, GL_DEPTH24_STENCIL8_EXT );
Luckily GL_DEPTH24_STENCIL8_EXT happens to have the same value as iOSs GL_DEPTH24_STENCIL8_OES"
But the layers are not always children of the "model root" node : there can be a matrix transform between "model root" and "layers parent", so I've added the name "Layers" on the node which contains all layers to easily retrieve the layers groups from application code."
Cocoa and when to use the old Carbon interface for the windowing system.
The old code had to be modified for every new OS X release to default to Cocoa.
The new code uses Carbon for <= OS X 10.4 and Cocoa on everything else."
- Also, a 'dontSaveNormals' was added. It allows to ignore normals when writing an STL file. For example, it is useful for me when writing an STL file for CFD simulations.
- Some comments and code formatting were improved (to be consistent with the formatting already used in the plugin).
- With 'separateFiles' option files are now named fooX.stl instead of foo.stlX
The changes have been tested on various STL, both ASCII and binary found on the net. The change was based on the trunk branch."
From Robert Osfield, changed assert in Piotr's code to a runtime check warning report.
This fixes problems with PolygonZ records where the previous code was reading past the end of the record since it thought it had M values even if it didn't. I suspect the problem that James McGlone had back in 2006 was the same but reversed, when he tried to simply comment out the check, which was a (correctly) refused submission.""
