OpenGl_CappingAlgo - move global variables to OpenGl_Workspace class fields.
OpenGl_View::ShaderSource::Source() - drop static for local variable.
OpenGl_Window - drop redundant global constant THE_DEFAULT_BG_COLOR.
OpenGl_Element destruction and resource deallocation methods now accept
a pointer to OpenGl_Context instead of a handle to avoid double deletion
of the context.
License statement text corrected; compiler warnings caused by Bison 2.41 disabled for MSVC; a few other compiler warnings on 54-bit Windows eliminated by appropriate type cast
Wrong license statements corrected in several files.
Copyright and license statements added in XSD and GLSL files.
Copyright year updated in some files.
Obsolete documentation files removed from DrawResources.
- OpenGl_Display - release GL resources correctly on closing views
- OpenGl_AspectFace, OpenGl_AspectText, OpenGl_AspectLine, OpenGl_AspectMarker - initialize OpenGl resources on demand, when context is available.
- Graphic3d_TextureRoot - use const modifier for GetId method to avoid asynchronous resource state at OpenGl.
- Do not call OpenGL functions if no active GL context has been left
- Reset thread's context before deletion for Mesa WNT
Graphical clipping:
- Use "Graphic3d_ClipPlane" to defined clipping for PrsMgr_PresentableObject (local clipping), for V3d_View (global clipping).
Get rid of old implementations:
- Remove Visual3d_ClipPlane.
- Port V3d_Plane to Graphic3d_ClipPlane core.
Selection Sensitives:
- Port "Matches" method to add full set of arguments (SelectBasics_PickArgs), including min-max depth coming from selector.
- Get rid of transient data for pair Matches -> ComputeDepth.
- Extend SelectMgr_ViewerSelector::LoadResult to work with local clipping, add virtual callbacks to compute globa/local depth clipping for picking.
Capping rendering algorithm:
- Recursive rendering algorithm for OpenGl_Groups.
- Introduced Rendering filter for groups.
Clipping plane management in TKOpenGl:
- Added OpenGl_ClippingState to OpenGl_Context.
DRAWEXE commands:
- Ported "vclipplane" command for new approach.
- Added "vsettexturemode" command for changing texture details in views (enable / disable textures).
Correct DownCast syntax (compilation error)
Fix new compiler warnings
tests/bugs/vis/bug22906 migrated to the new vclipplane syntax
