a2b94b9562 vcl: OpenGL code for adding preambles to glsl fragments now handles #version 
If you include the #version directive then it must be on the first non-comment
line in a glsl fragment. This is now handled.

df290c6345 make it possible to easily have variants of glsl programs 
Now it's possible to add a preamble to the compiled program, so there can
be just one program with #ifdef's inside and the small variants can be
selected using #define in the preamble instead of having several almost
identical programs.

a55f740045 include the unx part for getting OpenGL driver & device information 
desktop/unx/source/glxtest.cxx is taken directly from the Mozilla
project.

THe whole concept is taken from Mozilla and is based on starting an
early process that creates an OpenGL context. This prevents crashing
drivers to crash Libreoffice.

We read the information from the pipe as soon as we create the first vcl
Window. In that place we then decide if the device/driver combination is
blacklisted.

079c861f08 fdo#81237: 2D OpenGL charts was upside-down 
The problem is that LO drawinglayer uses a coordinate system
with an origin at the top-left corner of the screen, while
OpenGL uses a complete coordinate system (with all four
quarters, e.g.: allows negative values). The points in
LO are always positive values which means they are drawn
in the first quarter of the OpenGL coordinate system which
also means that the origin is at the bottom-left corner
of the scene. This difference causes the flipped scene.

* To solve that problem scale the projection matrix with -1.0f
along the y axis.
* glDisable(GL_CULL_FACE) is necessary to avoid dropping primitives
after scaling with -1.0.
* Since projection matrix mirrors also the textures we don't need to
do that inside the ConvertBitmapExToRGBATextureBuffer() method.
