QMatrix4x4 accepts data in row-major order, but returns them in
column-major order, which is not documented and because of that
I expected them to be in row-major order.
This commit fixes it and rewrites the shaders to apply the matrix
multiplications in the right order.
REVIEW: 100759
Adds a shader to render an untransformed scene. renderGLGeometry is not used any more and replaced by generated triangles stored in a GLVertexBuffer.
The GLVertexBuffer has a new attribute to decide whether a core profile compatible rendering has to be performed.
Currently windows and EffectFrames can make use of the new shader.
The shader contains a debug mode which colours all rendered fragments in green. It is currently enabled in scene_opengl.
Rendering transformed geometries (without shader) is currently broken.
