- changed the event tap code
- macos catalina 10.15 now requires user permission for “screen recording” to allow apps like pixelstick to see the contents of the screen. now fixed
- when building pixelstick with xcode versions 10 and above: the window is no longer transparent, so you only see pixelstick on a grey background covering the whole screen. this is now fixed.
 
if you have any issue make sure you uncheck and check the permissions for pixelstick in privacy:accessibility, privacy:input monitoring and privacy:screenrecording.

- fix for 0's displaying for location of circle and square in pixelstick panel for some people. this occurred if in the system preferences:mission control the item "Displays have separate Spaces" was unchecked. this was, as you can imagine, difficult to discover. we apologize for the delay. this version solves that. the sys pref can now be set either way. you don't need to change any settings.

a major upgrade is still on the way.

IMPORTANT: With version 2.11 of PixelStick now recommends that its default scale uses the
coordinates directly reported by macOS. Previously it scaled those coordinates
by a screen-dependent "backing scale" (typically 2x for Retina screens).
However the "backing scale" does not correspond to physical pixels because
macOS supports a variety of scaling options via Displays Preferences, none of
which change the backing scale reported by macOS to apps. For compatibility
with previous versions' saved coordinates, PixelStick will continue to apply
that scaling until you open PixelStick's preferences and select "Use macOS
coordinates".

[New] Reworked the loupe code so that the magnified screen images are much
crisper and do not include magnified copies of PixelStick's endpoints and
guides.
[Fix] Prevent the situation on some systems where the cursor appeared in the
endpoint and colour picker loupes (and thus was magnified and prevented colour
selection).
[Fix] Remove the red frame from accessibility element screen grabs.
[Fix] Prevent PixelStick from reporting the screen width as double the number
of pixels macOS reports. (This is precisely the problem of previous versions
of PixelStick using a Retina screen's backing scale.)
[Fix] Corrected the measurements PixelStick reports when moving PixelStick
from a Retina screen to a non-Retina screen.
[Fix] Redraw and, if necessary, adjust PixelStick's endpoints when the
display's scale is changed via Displays Preferences.
[Fix] Reduce duplication of some internal calculations, improving consistency
between unscaled and scaled measurements.

[Fix] Draw circle guides correctly on Retina screens.
[Fix] Improve behaviour when editing values directly in the palette.
[Fix] Double-click on the palette title bar only to collapse the palette

[new] Map mode for measuring angles increasing clockwise. When combined with setting the baseline to a vertical line, this is great for taking bearings on a map. [mod]
[new] manual updated and new location.
[Fix] Draw circle guides correctly on Retina screens.
[Fix] Improve behaviour when editing values directly in the palette.
[Fix] Double-click on the palette title bar only to collapse the palette. This means double click within the content of the palette now correctly selects the text to edit instead of collapsing the window.
[Comment] Thanks for all the user feedback. We really appreciate hearing about your suggestions, bugs, manual additions and changes. More good stuff to come...

[new] Remembers the last used scale and eye dropper settings.
[mod] compiled and optimized with xcode 7.2
[new] Can now measure angles relative to a non-horizontal baseline.
[mod] Angle and length now displayed with more precision (i.e. not rounded to integer values).
[mod] Compatible with Mac OS 10.6 - 10.11
[new] User preference setting for displaying or hiding the loupe shown when dragging points.
[new] User preference setting for displaying or hiding the grid inside the loupe (when the loupe is shown).
[fix] Loupe view now also works on OS X 10.6 (previously it only could appear on OS X 10.7 or higher).
[fix] Make closing the preferences window behave in a more standard fashion.
[fix] Restore the missing app icon and include hi-res versions.
[new] Support for the "Screens have separate Spaces" user preference added in OS X Mavericks.
[fixed] Color picker shows the wrong color in some screen arrangements, particularly when secondary screens are arranged higher or lower than the primary screen.
[fixed] Loupe not magnifying the correct area of the screen on secondary screens in some screen arrangements.
[fixed] Reset position can result in endpoints moving off-screen some screen arrangements.
[fixed] PixelStick does not extend into newly revealed screen space when screen arrangements are changed while PixelStick is running.
[fixed] Crash on OS X Mavericks and higher when selecting the "screen elements" ruler more than once.

[mod] updated graphics, icons and function for retina displays (thanks to user Damien).
[fix] cursors disappearing under "invisible rug". this happens when you use several 
	displays or simply change screen resolution (thanks to user Colin Murray's).
[fix] position of main panel was not saved in older versions of OS X (thanks to user Chris Pritchard).
[new] new icons.
[mod] optimized code and compiled with xcode 4.4.
[mod] improved documentation.
[new] signed by plum amazing with apple developer certificate to follow apple's latest security guidelines.
[new] gatekeeper turned on to follow apple latest security guidelines.
[new] added holding the command key to have the square move pixel away from the circle. so the ruler expands in size when you hold command key and hit the left or right arrow key
[new] added holding the command key to have the diamond rotate around the circle when you also hit the up or down arrow key
[new] added holding the shift key and clicking the arrow moves it 10 pixels/click. without shift key it moves the ruler 1 pixel at a time.
[new] to change the angle 1 degree add option key pressed. opt and arrow key changes the angle. circle is the center and square is the part that moves 1 degree
[new] the camera is the beginning of an advanced screenshot utility.
[new] you can click on the numbers in the palette to copy, change and edit them.
[mod] in the prefs. turn on/off the guides is instantly updated. you don't need to close the dialog first like in previous versions.
