identify a radius of the new corner;
adjust the top edge at least in part by removing a length of the top edge equal to the radius; and

identify a width associated with the textual content; and
display a side edge of the border at a third position that is based on the width.
7. The border generation system of claim 1 , wherein the textual content is included in a first frame, and wherein the at least one processor is further configured to render the bottom edge using a continuity indicator that associates the first frame with a second frame.
8. The border generation system of claim 7 , wherein the continuity indicator is a dashed line.
9. The border generation system of claim 1 , wherein the at least one processor is further configured to:
receive fourth user input that identifies additional textual content to be positioned between top and bottom edges of an additional border;
identify one or more common characteristics shared by the border and the additional border;
merge the border and the additional border to form a new border in response to identifying the one or more common characteristics; and
display the textual content, the additional textual content, and the new border.
10. A method comprising:
receiving first user input that identifies textual content to be positioned between top and bottom edges of a border, the textual content comprising a first plurality of glyphs;
receiving second user input specifying that the top edge is to be positioned relative to a maximum ascent, and that the bottom edge is to be positioned relative to a baseline;
receiving third user input that specifies top and bottom offset values;
identifying a first font used to render the textual content, the first font comprising a second plurality of glyphs that includes at least one of the glyphs included in the first plurality of glyphs;
identifying a second font used to render the textual content, the second font comprising a third plurality of glyphs that also includes at least one of the glyphs included in the first plurality of glyphs;
identifying a tallest glyph amongst the second and third pluralities of glyphs, wherein the tallest glyph has a maximum height, but is not included in the first plurality of glyphs;
displaying the top edge at a first position that is separated from the maximum height by the top offset value; and
displaying the bottom edge at a second position that is separated from the baseline by the bottom offset value.
11. The method of claim 10 , further comprising:
determining, based on the first position and the second position, a third position for a new corner where the top and bottom edges meet; and displaying the new corner at the third position.
12. The method of claim 11 , further comprising identifying a corner type for the new corner, the corner type comprising one or more of fancy, bevel, inset, inverse rounded, and rounded.
13. The method of claim 11 , further comprising:
identifying a radius of the new corner; adjusting the top edge at least in part by removing a length of the top edge equal to the radius; and adjusting the bottom edge at least in part by removing a length of the bottom edge equal to the radius.
14. The method of claim 10 , further comprising:
identifying a margin associated with the textual content; and displaying a side edge of the border at a third position that is based on a location of the margin.
15. The method of claim 10 , further comprising:
identifying a width associated with the textual content; and displaying a side edge of the border at a third position that is based on the width.
16. The method of claim 10 , wherein the textual content is included in a first frame, and wherein the method further comprises rendering the bottom edge using a continuity indicator that associates the first frame with a second frame.
17. The method of claim 16 , wherein the continuity indicator is a dashed line.
