Fix integer division issue\&.
.IP "\(bu" 2
Fix material and normal handling for indexed line set\&.
.IP "\(bu" 2
Fix resource lookup when HAVE_MULTIPLE_VERSION is enabled in CMake build script\&.
.IP "\(bu" 2
Fixed an transparency issue for indexed lineset\&.
.IP "\(bu" 2
Move constant data to read only data segment to reduce size of shared object library (see https://randomascii.wordpress.com/2017/01/08/add-a-const-here-delete-a-const-there)
.IP "\(bu" 2
Fixed numerous issues detected by static code analysis\&.

Fix broken ABI version on \&.so link\&.
.IP "\(bu" 2
Do not run programs for determining hash quoting to support cross compiling\&.
.IP "\(bu" 2
Fix testing for maximum texture size\&.
.IP "\(bu" 2
Removed obsolete ATI driver issue check\&. Do not check for ATI driver issues fixed long time ago (see issue #412)\&. We added environment variable COIN_GLGLUE_DISABLE_VBO_IN_DISPLAYLIST for compatibility with the old behaviour\&.
.IP "\(bu" 2
Fix underlinking against X11 in CMake build scripts\&.
.IP "\(bu" 2
Set GLSL shader version to 120 to avoid rendering issues with fog\&.
.IP "\(bu" 2
Enable non power of two textures for ATi and Intel by default\&. For those who are in need of the old behavior, an environment variable COIN_GLGLUE_DISABLE_NON_POWER_OF_TWO_TEXTURES has been added\&.
.IP "\(bu" 2
Do not disable VBO rendering for Intel graphics drivers anymore\&. Recent Intel graphics hardware is known to properly support VBO rendering\&. So we remove the code for disabling it by default\&.
.IP "\(bu" 2
Fix GLX glue trying to use NULL display, i\&.e\&. when a unix platform has a non-GLX context: usually Wayland, but also might be offscreen or maybe EGL-X11\&.
.IP "\(bu" 2
Fix operator arguments on some base types to use const references rather than copies\&.
.IP "\(bu" 2
Fixed incorrect rendering of \fBSoFaceSet\fP\&. Conditions when to render as VertexArrayObject were not properly checked\&.
.IP "\(bu" 2
Fixed incorrect line ending handling for Windows CR/LF\&.
.IP "\(bu" 2
Fixed incorrect closest point calculation for bounding boxes\&.
.IP "\(bu" 2
Applied some distribution patches from Fedora, Rosa, and Gentoo\&.
.IP "\(bu" 2
Added some class documentation and fixed numerous documentation issues\&.
.IP "\(bu" 2
cpack\&.d was made optional and disabled by default (add -DCOIN_USE_CPACK=ON to the cmake commandline to enable it)\&.
.IP "\(bu" 2
Reference line for text rendered with the built-in default font was changed (before: descender line, now: base line)\&. Thus text rendered with default font will appear a few pixels lower than before, but now consistent with text using non-default fonts\&. (see https://github.com/coin3d/coin/pull/368)
.IP "\(bu" 2
Fixed crash when call to cc_flww32_get_bitmap() failed\&.
