* @brief LLTexture definition
|
|
*
|
|
* This class acts as a wrapper for OpenGL calls.
|
|
* The goal of this class is to minimize the number of api calls due to legacy rendering
|
|
* code, to define an interface for a multiple rendering API abstraction of the UI
|
|
* rendering, and to abstract out direct rendering calls in a way that is cleaner and easier to maintain.
