of the OverlayNode.
I change the overlay subgraph dynamically and when I remove all the
subgraph nodes that is inside the current main camera FOV (others
outside still exist), the overlay texture does not update because of the
early return in the traversal. I then get a kind of ghost texture moving
around the terrain.
The attached file fixed the problem for me, but I'm not sure if it is
the best way to address the problem."
two lines has to be included into the Image.cpp in the
computeNumComponents(...) method:
case(GL_RGBA16F_ARB): return 4;
case(GL_RGBA32F_ARB): return 4;"
It does not like that the prototype of ClipNode::setStateSetModes() differs
from implementation of that function in the constness of the second
parameter.
On SunOS it compiles fine, but I get link errors when the variant that is
declared in the header is referenced.
The attached src/osg/ClipNode.cpp file removes the const qualifier from the
implementation to match exactly the prototype in the header file.
The file is based on revision 7386 as of today.

- GL2Extensions, Program and Program.cpp
Features:
- Support for fragment output binding. (e.g. You can now specify in the fragment shader varying out vec3 fragOut; fragOut = vec3(1,0,1); to write to the fragOut variable. In your program you call glBindFragDataLocation(program, 1, "fragOut") to bind the fragOut variable with the MRT 1 - GL_COLOR_ATTACHMENT1_EXT)
- new methods Program::add/removeBindFragDataLocation Program::getFragDataBindingList
"
- Implementation of integer textures as in EXT_texture_integer
- setBorderColor(Vec4) changed to setBorderColor(Vec4d) to pass double values
as border color. (Probably we have to provide an overloading function to
still support Vec4f ?)
- new method Texture::getInternalFormatType() added. Gives information if the
internal format normalized, float, signed integer or unsigned integer. Can
help people to write better code ;-)

Futher changes to this submission by Robert Osfield, changed the dirty mipmap
flag into a buffer_value<> vector to ensure safe handling of multiple contexts.
local function pointer to avoid compiler warnings related to case void*.
Moved various OSG classes across to using setGLExtensions instead of getGLExtensions,
and changed them to use typedef declarations in the headers rather than casts in
the .cpp.
Updated wrappers
