osg::Image::readPixels to encapsulate glReadPixels.
Reordering of includes in include/osg/Fog and include/osg/Light to remove silly warnings under Visual Studio.
it now maintains references to the last applied matrices, automatically doing
lazy state updating. This simplifies the various places in the OSG which
were previously doing the applying, add paves the way for managing the
projection matrix within the scene graph.
Remove MemoryAdapter and mem_ptr as they arn't being used, and can potentially
confuse users by their existance.
osg::Texture. The values default to 0, and in this state they are
sizes of the glTexSubImage2D are taken from the source image size. This
allows the previous setup with no settings for subload size to work as
before.
easier to specify which modes and attributes have been modified without
the user requiring to know to what value, or to have an equivilant attribute
to pass to the have_applied_attribute method. The original have_applied(mode)
and have_applied(attribute) methods have been renamed have_applied_mode(),
have_applied_attribute() as this was required to prevent the mode and type
values colliding during compile (it was causing a compile error when the method
names were the same.)
much more of the core texture setup code. This largely invloved paramterizing
the applyImmediateMode, which has also been rename applyTexImage to reflect
its functionality better.
mode by using a _texParamtersDirty flag in combination with an
applyTexParamters(State&) method which does the paramters setting in one
tidy bundle. This new implementations replaces the CompileFlags submitted
yesterday.
Simplified NodeCallback by remove osg::NodeCallback::Requirements as they
are no longer needed.
Fixed comments in Drawable.
Put guards around cosf definations so that they are only used under Win32/Mac.
Fixed warning in CullVisitor.
