* Fixed uploading of textures of certain sizes.
* When glTexSubImageND is used, track the set of changed tiles in a
bit vector and upload only dirty tiles later. This should improve
the performance of dynamic light maps and gl movie player plugins.
* Renamed debug item "lru" to "tex". Indicate which levels are
uploaded completely or partially.
