 -DUSE_PANIC_ON_PHOTO_ALLOC_FAILURE.  Code linked using Stubs against

+.SH BUGS
+The \fBTk_PhotoImageBlock\fR structure used to provide image data to
+\fBTk_PhotoPutBlock\fR promises great flexibility in the layout of the
+data (e.g. separate planes for the red, green, blue and alpha
+channels).  Unfortunately, the implementation fails to hold this
+promise.  The problem is that the \fIpixelSize\fR field is
+(incorrectly) used to determine whether the image has an alpha channel.
+Currently, if the offset for the alpha channel is greater or equal than
+\fIpixelSize\fR, \fBtk_PhotoPutblock\fR assumes no alpha data is
+present and makes the image fully opaque.  This means that for layouts
+where the channels are separate (or any other exotic layout where
+\fIpixelSize\fR has to be smaller than the alpha offset), the alpha
+channel will not be read correctly.  In order to be on the safe side
+if this issue will be corrected in a future release, it is strongly
+recommended you always provide alpha data - even if the image has no
+transparency - and only use the "standard" layout with a
+\fIpixelSize\fR of 2 for grayscale and 4 for RGB data with
+\fIoffset\fRs of 0, 0, 0, 1 or 0, 1, 2, 3 respectively.

+Tk supports all of the NSColors in the macOS System ColorList.  The
+convention for naming these colors is that the Tk name is generated by
+capitalizing the macOS name and adding the prefix "system".  On OSX
+10.14 (Mojave) and later many of these "semantic" colors will appear
+differently depending on whether the NSWindow in which they are used has
+the Aqua or DarkAqua appearance.  The System ColorList differs between
+releases of macOS and some colors, such as systemLinkColor and
+systemControlAccentColor, are simulated on older systems which did not
+provide them.  All of the colors below are available on all supported
+macOS releases, but newer systems will support additional colors.
