* Locked resources are now guaranteed, though they currently share memory limits with the cache, so be certain to release them when you're done.
* RetrieveQuad now returns different quads for different resource names, regardless of if they share size and position.
This is pretty major, so there'll probably be something wrong with it... even though I did spend a few hours looking.
NOTES:
* If you've Retrieved it, don't delete it--- Use resources.Release(Whatever).
Textures automatically release subordinate quads.
* Most of the time, use resources.RetrieveQuad to grab a quad. Should handle everything for you.
RetrieveQuad will load the required texture, if needed.
Only managed resources have a resource name ("back", "simon", etc).
Managed resources can be retrieved with GetTexture/GetQuad/GetWhatever.
Non managed quads lookup by position/dimensions, defaulting to the whole texture.
* Use resources.RetrieveTexture only when you need to do something special to it.
Calling retrieve texture with RETRIEVE_MANAGE will permanently add a texture to the manager
RETRIEVE_LOCK and RETRIEVE_VRAM will lock a texture. It will not leave the cache until
Release(JTexture*) is called, or as a last resort during cache overflow.
* Try to only store (as a class member) pointers to textures retrieved with RETRIEVE_MANAGE.
All others may become invalid, although locked textures do have a high degree of stability. It's
pretty safe to store a locked texture if you're not going to load much between uses.
There's a lot going on here, so I might have missed something... but it runs through the test suite alright.
TODO:
* When called without any arguments, RetrieveQuad sometimes leaves a thin border around the image.
This can be bypassed by specifying a quad one or two pixels less than the image size. Why?
* I've had a crash while runing the Demo mode, something to do with receiveEventMinus?
This hasn't exactly reproduced on a clean SVN copy, (being a hang, rather than a crash) so
I've probably done something to worsen the problem somehow? I'll look into it tomorrow.
* Clean up lock/unlock system, memory usage. Streamline interface, consider phasing out calls using GetWhatever() format.
