The invention claimed is: 1. A method of making a glazing subassembly, the method comprising: providing a glass panel having first and second major surfaces; providing a sheet of masking material; disposing the sheet of masking material over the glass panel first surface; and cutting a plurality of rectangular closed paths through the masking material with a laser beam, each closed path defining a central region disposed within a peripheral region. 2. A method as in claim 1, further comprising removing the masking material from the peripheral region while leaving the masking material in the central region. 3. A method as in claim 1, further comprising removing the masking material along the closed paths, leaving the masking material to remain in the central regions. 4. A method as in claim 3, further comprising providing and disposing muntin bars over at least some of the remaining masking material. 5. A method as in claim 1, wherein the glass panel has edges having a peripheral zone within the edges, and a central zone within the peripheral zone, wherein the cutting step forms a peripheral closed path between the peripheral zone and the central zone. 6. A method as in claim 5, further comprising removing the masking material from the peripheral zone, leaving the masking material to remain in the central zone. 7. A method of making a glazing subassembly, the method comprising: providing a glass pane including first and second major surfaces, each of the first and second major surfaces having a central region and a peripheral region; disposing over the first surface of the glass pane a sheet of masking material dimensioned to cover the central region and at least a portion of the peripheral region; cutting through the masking material along a path between the central region and the covered portion of the peripheral region, so as to form a peripheral masking material strip; removing the peripheral masking material strip while leaving the central region covered; and disposing the glass pane within a frame such that at least part of the frame overlies an edge of the masking material that covers the central region. 8. A method as in claim 7, wherein the edge of the masking material overlaid by the frame has a width of less than about 2 millimeters. 9. The method as in claim 7, wherein the sheet of masking material is further dimensioned to leave a pair of opposing portions of the peripheral region of the first surface of the glass pane free of masking material when the sheet is disposed over the first surface of the glass pane. 10. A method of making a glazing subassembly, the method comprising: providing a glass panel having first and second major surfaces; providing a sheet of masking material; disposing the sheet of masking material over the glass panel first surface; and cutting a plurality of closed paths through the masking material with a laser beam, each closed path defining a central region disposed within a peripheral region. 11. A method as in claim 10, further comprising removing the masking material from each of the peripheral regions defined by the plurality of closed paths. 12. A method as in claim 11, further comprising disposing at least one muntin bar over at least one of the peripheral regions.
