hi folks, while porting inventor to aix-platform, i found a little bug in the SoXtRenderArea: The renderarea assumes that the transparency index of an overlay is always index 0. well this is true at least for sgi- and nvidia-linux-machines, but not for aix-machines - they have an index of 0xff. fortunately it is possible to ask glx for the right index. i included it in the patch. additionally, i added support for installing inventor different to $IVROOT/usr/[bin|lib|man|share|demos], i.e. you can install inventor now in $IVROOT/$PREFIX/[bin|lib|man|share|demos] just change the PREFIX variable in make/ivcommondefs. note, that only those files are patched which are actually installed, e.g. apps/demos, but the mentor-examples are not patched so far. i hope this patch is useful and get its way into cvs. gerd ps: next week i think i have a patch for a port to aix
