Thanks to Norbert Vischer, the close(pattern) macro function closes windows whose title matches 'pattern'. Non-image windows, like "Roi Manager" have to be specified without wildcards. For text windows, wildcards are allowed if 'pattern' ends with ".txt", ".ijm" etc. Use close(pattern, "keep") to close only unchanged windows.
Thanks to Michael Schmid, added the Recorder.fixString() method, which is used to escape strings passed to the recorder.

New in ImageJ 1.51q (Sep 21, 2017)

Plot enhancements, thanks to Michael Schmid: ? Plots saved as tiff or zip include the data, so the plot range can be modified (zooming, etc.) and the data can be listed after loading the plot from a file.
Changing the axis or label font size of a plot keeps the image size constant and modifies the plot frame size (previously, the plot frame size was constant).
Slightly more space for numbers at the left, enough for scientific notation. ImageJ switches to a smaller font if more significant digits are required.
Added Plot.getFrameBounds(x, y, width, height) macro function.
The default font for plots is now Arial, not Helvetica (Arial is available on more platforms).
When opening a plot on a computer where a given font is not available, try to replace fonts by similar ones. This should make the appearance on different platforms more similar.
The ImageProcessor getStringWidth() and getStringBounds() methods use the more accurate GlyphVector class.
Thanks to Norbert Vischer, the Edit>Selection>Straighten and Image>Duplicate commands work with rotated rectangle selections.
Thanks to Jerome Parent, added the Image>Stacks>Plot XY Profile command.

Improved Plot class with many new features (demo macro):
Plot windows can be resized.
Use Image>Zoom>View 100% or More>>Reset Format to revert to the size defined in Edit>Options>Profile Plot Options.
Image>Zoom>In, or the '+' key, zooms in (both x&y) and Image>Zoom>Out, or the '-' key, zooms out.
Put the cursor below the x axis to zoom in/out horizontally and put it left of the y axis to zoom in/out vertically.
With the cursor below or left of the plot, arrows appear, which can be clicked on to to shift the limit.
With a selection, the '+' key, Image>Zoom>In and Image>Zoom>To Selection set the data range to the selection.
Image>Zoom>Original Scale reverts to the original data range.
Image>Zoom>Scale to Fit sets the scale to fit all data.
Use the hand tool (or drag with the space bar down) to shift the display range.
Select whether axes should have ticks, grids etc. in More>>Axis Options.
Adjust the font size in More>>Axis Options or in Profile Plot Options (for future plots).
Plots can now have a legend, and with "Legend Position" set to "Auto", the legend tries to not cover any data.
You can create a high-resolution (publication-quality) version of a plot by using the More>>High-Resolution Plot command.
The "Apply" button in the Image>Adjust>Brightness/Contrast dialog works with 16-bit images.
The getResult() macro function works with tables that are not named "Results".
The "Save..." button in plot windows uses the "File extension for tables" from Edit>Options>Input/Output as the default extension.
Image>Adjust>Color Threshold uses the ColorSpaceConverter class (Image>Type>Lab Stack) to do RGB to Lab conversions.
Fixed a bug that sometimes caused 16-bit to 8-bit conversion of composte color images to fail.
Added the getValue("results.count") macro function.
Added the TextPanel.getOrCreateResultsTable() method.
Fixed a bug that caused the default "File extension for tables" in the Edit>Options>Input/Output dialog to be set to ".csv" when it was actually ".xls".
Fixed a bug that caused an exception when saving composite selections with properties.
Fixed a bug that caused the Make Binary and Convert to Mask commands to not work correctly with thresholded RGB images.
