Change History (most recent first):

|
|
<3> 8/4/92 DCL Changed the textLen parameter to textLength in the prototypes
|
|
for PortionText, VisibleLength, PixelToChar & CharToPixel.
|
|
<2> 5/29/92 DCL Moved StdText from QuickDraw to QuickDrawText and fixed up some
|
|
comments.
|
|
<1> 5/5/92 DCL first checked in
