Wide lines + line stipple deprecated API replacement

The patch contains an implementation of the wide lines and the line stipple that is necessary for OpenGL upgrade.

For the implementation I have chosen the geometry shader because it required minimum changes for the wrapper calls and such implementation is the best for the "basic shader" architecture.

There are few shortcomings that can be corrected in future. They all are related to the fact that the lines in one strip are not connected with each other. So the stipple pattern is not continuous on the common vertex of two lines. There is also no continuity of form (each line is an independent rectangular).
But the advantage is that even outdated glBegin, glVertex work! Though with the above restrictions.
Continuity of form and stipple can be implemented with additional attributes, and it will require more changes in calls.

At the moment, the patch replaces calls for some "gestures". It works satisfactorily for "cross" or "rectangular" and not so good for "lasso" and "circle" due to the above-mentioned shortcomings.

Don't forget to set USE_GLSL to true for testing.

Fix T47705: Freestyle line glitch.

The addressed issue is a regression from Blender 2.75, after the internal
switch from double to single precision floating-point numbers in the
Freestyle code base. Face normal calculations require the higher
precision during the computations, even though the results can be stored
as single precision numbers.

Cleanup: Typo fixes after BVH commits.
