Corrected text clipping to cell bounds, and adjusted screen to
...
a half-pixel offset that centers coordinates on pixels, so single-
pixel objects like cell boundaries or the crosshair will be drawn
a single pixel in width.

Applied an upside-down scale transformation to the pattern matrix,
...
otherwise patterns end up upside-down relative to other graphics
interfaces.

Corrected typo in call to cairo_surface_destroy, incorrectly
...
written cairo_destroy_surface (fails to run with Tcl <= 8.5,
runs with Tcl 8.6 and "load -lazy" but then creates a
potential crash condition).

Finished the implementation of Cairo 2D graphics (yay!).
...
Specifically, fixed the initial background, display of text,
reinstated supercolor values, and fixed the backing store
coordinates.

Corrected problems having to do with color (blue and green were swapped)
...
and incorrect call to cairo_set_source_rgba which is in an unused
function and has no effect except with versions of Tcl less than 8.6
where "load -lazy" is not available and unknown functions cause
immediate exit. Cleaned up remaining references to OpenGL in the
Cairo code, and updated the copyright and acknowledged Chuan Chen, who
coded the Cairo interface. No attempt yet to deal with memory leaks
caused by calling Cairo "create" functions without the accompanying
"destroy" functions.

Changed the offscreen-rendering handling in SetProjection to be
...
more like the Tk/X11 model than the OpenGL model, since Cairo
isn't picky about pixmaps.
