Disable releaseUITextures cvar

[Ketho]

This is kind of a follow-up to this thread: GetTexture() returns nil on unloaded textures

I've been trying to update LargerMacroIconSelection for the Equipment Manager icons too, but you have to show the parent frame(s) first in order to get the textures

• At first I tried showing and hiding it, but then it would give an error
  

  CharacterFrame:Show()
  GearManagerDialogPopup:Show()
   
  for _, child in ipairs(regions) do
      if child.GetTexture then
          if child:GetTexture() == "Interface\\MacroFrame\\MacroPopup-TopLeft.blp" then
              -- dostuff
          end
      end
  end
   
  CharacterFrame:Hide()
  GearManagerDialogPopup:Hide()

  Message: ..\FrameXML\CharacterFrame.lua line 191:
     attempt to perform arithmetic on a nil value

  _
• Then I tried ToggleCharacter("PaperDollFrame"), but it would throw errors on login
  
  

  ToggleCharacter("PaperDollFrame")
  GearManagerDialogPopup:Show()
   
  for _, child in ipairs(regions) do
      if child.GetTexture then
          if child:GetTexture() == "Interface\\MacroFrame\\MacroPopup-TopLeft.blp" then
              -- dostuff
          end
      end
  end
   
  ToggleCharacter("PaperDollFrame")
  GearManagerDialogPopup:Hide()

  Message: ..\FrameXML\PaperDollFrame.lua line 1727:
     Usage: GetSpecializationRole(specIndex[, isInspect[, isPet]])

• Now that I fail to work around it, my last resort is to just disable the releaseUITextures CVar
  But since Blizzard wants UI textures to be freed up when not visible, can I get away with doing that?
  
  Would the increase in memory (or any performance hit) be significant?
  

  if GetCVar("releaseUITextures") == "1" then
      SetCVar("releaseUITextures", 0)
      -- ask the user if they want to do a /reload
      -- for releaseUITextures to be properly disabled, so we can grab our textures
  end

* I haven't yet checked into setting it up once the GearManagerDialogPopup is actually being shown, instead of at player login. Maybe that will also work...
