- add translation context for operator, menu, panel and etc. and their associated properties.
- improve some name and description but not finished.
- move reset BME material function inside BMEMaterialsHelper.
- rename variable of collection visitor in BME adder operator for clear meaning.
- replace some message box to report in ballance elements reset operator, BME materials reset operator and rail UV operator
- move rail creation function into an individual file, UTIL_rail_creator.py
- add flip options for screw rails. this allow user to create any types of screw rail they needed.
- add default rail material when creating rail.
* add Rail material in bme material.
- remove negative screw radius feature when creating curve rail.
* originally negative screw radius will cause normal flip issue when creating.
* however, negative screw radius feature can no fulfill each shapes of screw style. it is more convenient using blender mirror feature after creating screw rail.
* thus I remove this feature, not fix it (I can fix it).
- fix issue that blender 4.2 lost use_auto_smooth and calc_split_normals. (it almost works but not perfect. still need more debugging)
- remove depracted material blend_mode. use modern one instead. (the modern setting make me consufes but it works)
- add extra transform for rail creation.
- remove scale from extra transform because it is rarely used. because Ballance can not handle the physicalization of scaled object.
bring ballance virtools helper used fix_texture (renamed as fix material to correspond with the real object operated by this function) into blender plugin.
