Reload Texture/Force Load Texture Feature

I have little understanding of how the texture download system in sl really works, but I've wanted this feature (or something like it) for a long time. If anyone with more technical knowledge can add to or help develop this idea I welcome the help. Unless this is totally debunked I will propose this feature after I bang the bugs out of it.

---------------
WHAT IT DOES:
Basically what this feature would do is force the reloading of a texture, giving that texture priority over downloading all other files (until the download is complete).

WHY IT'S GOOD:
Lots of times I have been in the situation that one prim, the ground or a person just stays grey indefinately (until relogging or teleporting out and back in) or takes a really long time to load. It would be nice to be able to force the loading of this texture. Relogging or teleporting in and out takes time that a reload command could prevent because I only want to reload that one texture, not the entire area.

WHERE IT GOES:
For the land it could be on the top pie menu when right clicking (as there is a blank option there).

For prims maybe it could be part of the texture tab of edit mode (since that pie menu is pretty full already)

For your avatar maybe (when right clicking) a more > option is needed that would have this and maybe some of the other options in it (like teleport home or something fun like that

For other's avatars it could be after the more > option as I believe there are some spaces there.

It would be better to just fix the unloaded texture issue, but this could be a debug option at least.
