- * The Loading Window that is opened Immediately after Forge starts.
- * It is called from the ModDirTransformerDiscoverer, the soonest method that ModLauncher calls into Forge code.
- * In this way, we can be sure that this will not run before any transformer or injection.
- *
- * The window itself is spun off into a secondary thread, and is handed off to the main game by Forge.
- *
- * Because it is created so early, this thread will "absorb" the context from OpenGL.
- * Therefore, it is of utmost importance that the Context is made Current for the main thread before handoff,
- * otherwise OS X will crash out.
- *
- * Based on the prior ClientVisualization, with some personal touches.

- * A very simple, Mojang inspired BufferBuilder.
- * <em>This has been customized for 2d rendering such as text and simple planar textures</em>
- * <p>
- * Not bound to any specific format, ideally should be held onto for re-use.
- * <p>
- * Can be used for 'immediate mode' style rendering using {@link #draw()}, or
- * upload to external vertex arrays for proper instancing using {@link #finishAndUpload()}.
- * <p>
- * This is a Triangles only buffer, all data uploaded is in Triangles.
- * Quads are converted to triangles using {@code 0, 1, 2, 0, 2, 3}.
- * <p>
- * Any given {@link Format} should have its individual {@link Element} components
- * buffered in the order specified by the {@link Format},
- * followed by an {@link #endVertex()} call to prepare for the next vertex.
- * <p>
- * It is illegal to buffer primitives in any format other than the one specified to
- * {@link #begin(Format, Mode)}.
