This rectangle is the opengl context shape as provided
by the GLEventListe reshape method.

This rectangle is in GL ViewPort coordinate system.
(0,0) is at the lower left corner, X increasing right, Y increasing up, all in pixels units.

@return Rectangle, never null, do not modify
Rectangle getGLRectangle ()


This rectangle is a subset of the GL rectangle.
It must be used by all GL processes.

This rectangle is in GL ViewPort coordinate system.
(0,0) is at the lower left corner, X increasing right, Y increasing up, all in pixels units.

@return Rectangle, never null, do not modify
Rectangle getViewRectangle ()


return  time in nanosecond at the moment the display was called
long getTimeNano ()


return  time in seconds at the moment the display was called
float getTimeSecond ()


return  time in nanosecond between the previous render and this one.
long getDiffTimeNano ()


return  time in seconds between the previous render and this one.
float getDiffTimeSecond ()


OpenGL object associated to this context.
return  GLAutoDrawable
GLAutoDrawable getGLDrawable ()


OpenGL object associated to this context.
return  GL

GLExecutable are tasks run in the OpenGL thread.
Unlike phases, GLExecutable are run only once before being forgotten.
param  executable task to execute
void addTask (GLExecutable executable)


Sequence of phases executed in this process.
return  Sequence of Process
Sequence getPhases ()


Tracker object to avoid GPU resource index conflicts, memory statistics,
or act as a bank of resources.
return  GLResourceManager never null.
GLResourceManager getResourceManager ()


Record phases statistics.
return  GLStatistics
