Effect of Upper/Lower Case Primitives/Subfiles

[Eugen]

This is NOT an error in the parts. The LDraw format is case-insensitive. I personally would argue against editing existing parts simply to change the case in their type 1 lines.

Honestly, it would be much better keep all LDraw files names lower-cased.

As upper-cased names such as "NAME.DAT" came from DOS-era and upper-cased file extension with mixed case file name as "Name_L.LDR" came from MS Windows. Few related threads:

• https://github.com/leozide/leocad/issues/302
  
• https://forum.solidworks.com/thread/213933

Also its strange that "complete.zip" include "LDConfig.ldr" & "LDCfgalt.ldr", but its online versions available as "LDConfig.ldr"/"LDCfgalt.ldr" AND "ldconfig.ldr"/"ldcfgalt.ldr":

• http://www.ldraw.org/library/updates/complete.zip
  
• http://www.ldraw.org/library/official/LDConfig.ldr
  
• http://www.ldraw.org/library/official/LDCfgalt.ldr
  
• http://www.ldraw.org/library/official/ldconfig.ldr
  
• http://www.ldraw.org/library/official/ldcfgalt.ldr

So, I argue to use only lower-case naming for file names & extensions for all LDraw files.
