- Added osgviewerCocoa example to APPLE builds
- Fixed corrupt Xcode project generation with CMake 2.6 dealing with ADD_DEFINITIONS and CMake Policy CMP0005 on Leopard
- Resolved CMP0006 warning for examples and programs by setting BUNDLE DESTINATION to same as RUNTIME DESTINATION with CMake 2.6
- Fixed freetype plugin on Leopard to avoid OpenGL linking problem
- Figured out how to use a custom Info.plist included in the project (see osgviewerCocoa application CMakeLists.txt)"
It contained a bug that would cause freed memory to be written again.
Specifically, in FreeTypeLibrary::~FreeTypeLibrary(), calling
font->setImplementation(0); deletes the content pointed to by the
fontImplementation pointer, while the line the immediately follows
tries to access it.
My fix is to make the second instruction part of an else clause rather
than always executed. This way, the fontImplementation->_facade = 0
instruction is only executed when the font implementation is not set
to 0 before (although I have no idea what it is here for and if this
code path is ever followed, since I don't know the plugin's internals
very well).
Attached is the modified FreeTypeLibrary.cpp file."
It should not be introusive to any other palatform apart MSVC, but in order to link to debug-specific libs
I had to change plugins CMakeLists to differentiate debug/release linkage, I have used the same macro used in core libs
Now the macro used for plugin and examples linking test for existance of TARGET_LIBRARIES_VARS
that holds the names of the variables that have to be used for linking"
// GT: fix for symbol fonts (i.e. the Webdings font) as the wrong character are being
// returned, for symbol fonts in windows (FT_ENCONDING_MS_SYMBOL in freetype) the correct
// values are from 0xF000 to 0xF0FF not from 0x000 to 0x00FF (0 to 255) as you would expect.
// becuase Microsoft uses a private field for its symbol fonts ........

readFontStream() to load fonts from a std::istream, rather than from the
local filesystem by name. Such a call may be used, for example, if the
user has a font fetched over a network, or a font available in memory
without a correspondng filename.
The changes implement the new function by following the corresponding code
for readFontFile(). readFontStream() reads a stream into memory, and
holds that memory for FreeType.
As a basic test, I mangled the osgtext example to use
readFontStream(std::ifstream("font")) in lieu of a readFontFile call, and
the modified example ran completely."
instead of osgDB::Registry where it original lay. This has been done to allow
fileName strings to be encode data rather than just file names, such as one
requires when using PagedLOD along with plugins for doing dynamic tesselation.
that it creates, rather than have osgText::Font::readFontFile() use the
osgDB::Registry object cache.
This has been done to prevent problems when users flush the object cache,
which was causing a dangling pointer.
