Enhancements

New option for calculating bounding. A new option for called “consider bounding” has been introduced for Filter_Circumcuboid_By_Path, Filter_Circumsphere_By_Path, and their double-precision variants. This option means in-place highlights are accounted for when calculating bounds, even when a highlight style would otherwise make that object invisible.

New option to consider highlights in bounding operations. A new option is available for users when calling “Filter_Circumcuboid_By_Path”, “Filter_Circumsphere_By_Path” and their double versions. The option is “consider highlights”. The new option is off by default, and it is not compatible with the “minimal” option (if minimal is specified, then the consider highlights option is ignored). Specifying “consider highlights” makes it so in-place highlights are accounted for when calculating bounds. In-place highlights can make geometry visible or turn it invisible, and therefore can impact the boundings.

OpenGL2_Mesa driver. A new driver is available, based on OpenGL Mesa. This is a software driver meant for systems without GPU hardware. See the Device Guide for more details.

New option for managinging large translations. A new option, HInputHandlerOptions::m_bPRCExtractLargeTranslations is now available. When the option is enabled and a translation is found during an Exchange import which is large enough (relative to model size) to cause visual artifacts due to loss of precision, that translation is removed.
