|
* OGLTextRenderer.drawGlyphList(), and OGLMaskFill work properly when the
|
|
* operation parameters exceed the capacity of the render queue. With the
|
|
* single-threaded OpenGL pipeline, there are some operations that require

|
* a separate buffer to be spawned if the parameters cannot fit entirely on
|
|
* the standard buffer. This test exercises this special case.
