TextOverflowMode

Controls how text that does not fit inside the available rectangle is truncated. Carried by TextRendering.OverflowMode.

Constant	Value	Description
tbAllowPartialChars	0	Truncate at the available width, allowing the final glyph to be clipped mid-character.
tbDisallowPartialChars	1	Truncate at the last fully-visible character; no half-glyph at the edge. Used by WaynesTextBox so the caret never falls between glyphs of a surrogate pair.
tbAppendEllipsis	2	Truncate at the last fully-visible character and append … if any characters were dropped. The default for newly-constructed TextRendering objects.
tbShrinkToFit	3	Reduce the rendered font size until the entire string fits without truncation. Used by WaynesTimer so its design-time clock glyph scales with the control.
