Class for drawing 2D primitives using OpenGL 1.1+.
This class takes care of drawing the 2D primitives for the vtkContext2D class. In general this class should not be used directly, but called by vtkContext2D which takes care of many of the higher level details.

bool vtkOpenGLContextDevice2D::SetStringRendererToFreeType | ( | ) |
Force the use of the freetype based render strategy. If Qt is available then freetype will be used preferentially, otherwise this has no effect. Returns true on success.
bool vtkOpenGLContextDevice2D::SetStringRendererToQt | ( | ) |
Force the use of the Qt based string render strategy. If Qt is not available then freetype will be used and this will return false.
bool vtkOpenGLContextDevice2D::HasGLSL | ( | ) |
Check whether the current context device has support for GLSL.
