LDGLData merged into GLRenderer since it only deals with one document now. GLRenderer generalised from rendering documents to models.

Made a new renderer be created for each document, instead of reusing the same renderer for all documents.

Simplified GLRenderer::convert3dTo2d. The multiplication with the modelview matrix is not necessary, it's identity all the time... with that, I think the function makes much more sense now.

- Use a QGenericMatrix to store the matrix, instead of a C array

Changed from GLdouble to GLfloat. Apparently the performance difference is greater on the GPU..? It doesn't really matter but let's be consistent.

GLRenderer::clampAngle is no longer used as of the previous commit so we can do away with it.

Switched from euler angle rotation to matrix rotation. Gimbal lock is now broken.
