* @brief A class for managing an OpenGL framebuffer and attached texture
|
|
*
|
|
* The GPU pipeline will frequently need framebuffers for drawing onto textures. The TextureBuffer is a convenience
|
|
* class to handle the creation, management, and destruction of a framebuffer with a texture attachment.
|
|
*
|
|
* After creating a new TextureBuffer, call Create() when a valid OpenGL context is available.
