// Description : This class maintains a linked list of BufferContexts
|
|
// that might be allocated on the graphics card in some
|
|
// context. There is a different BufferContextChain for
|
|
// resident textures, active textures, evicted textures,
|
|
// etc.
|
|
//
|
|
// The primary purpose of this class is to facilitate
|
|
// PStats reporting of graphics memory usage.
