Looks like at some point I modified how "darkened" inactive powers worked and ended up drawing two copies of the darkened power counter for each inactive power. "runebg" is superfluous since we're just setting the color of the actual counter to black and partially transparent instead. For some power counters, such as Paladins, the runebg texture was actually wrong and drawing the entire atlas rather than just the texture we wanted.
Destruction Warlocks have a PowerMax of 1000 and apparently trying to create that many graphical frames blows something up really quick. In 7.0, everyone's runes are discrete objects, so I was trying to ensure that the graphical representations of a given power were ready at all times, but didn't consider the pre-7.0 case where this calculation would lead to an absurd number of "runes".
This change also fixes an errant CreateFrame() in UpdateRunePower() that was supposed to be self:CreateFrame(). CreateFrame() was just creating a nameless, parentless frame for no reason at all. Good job, me. This isn't C++.
Right now most ClassPowerCounter child classes are doing this work themselves, but they don't need to be. Some cleanup could be done there if anyone ever felt like doing it. (I did a tiny bit with Shards and Chi, but there's more to be done)
- Fixed the fifth chi not always drawing immediately when changing specs to one that grants an additional chi.
- Registered harmony power for the UNIT_POWER_FREQUENT event since that's what Blizzard's version does.
- Added basic support for Demonology spec (Demonic Fury) Warlock power.
- Fixed a bug or two in Warlock power presentation when un-speccing or learning a new spec after having been without a spec.
- Added support for hiding Warlock power until the requisite spell has been learned because apparently (after looking at Blizzard's code) you can have the spec without having the spell that builds up the power associated with the spec. Okay.
- expanded range of class power counters (shards, holy power) by request
- fixed lacerate and sunder count modules to work with 3 max charges instead of 5 as per the new patch (these *really* need to go away and be auto-replaced by custom counters...)
- yet another fix for text sometimes displaying the unit name for PetHealth
- fixed how the 'second highest threat' bar is drawn so that it actually works with all textures
- fixed "show incoming heals" option to be properly toggleable on 4.0 (bad conditional on the 'disabled' option)
- hid "cooldown mode" option on the totems module since there was never more than one choice
- added shard bar inheriting from ClassPowerCounter. same basic functionality as the holy power module: graphical mode that shows the default shards and numeric mode that just displays a count of active shards
