finnboeger fce694df28 Add a cursor (#46) ... * Added cursors * Prepare cursor code for future settings to toggle cursors on or off. Let cursor be the color the person has currently selected * fix cursor on mobile (still won't display it in most cases as there is no hover on mobile but at least it won't throw errors) * use correct size for cursor * throttle cursor update rate to dramatically improve performance by eliminating congestion * fix remote cursor size on desktop * show own cursor by default and renove offset * use svg as mouse cursor for pencil to be able to apply a reduced opacity to it and view our cursor * don't throttle local cursor * throttle local cursor at an independent higher rate. This could be made user adjustable for low power devices * remove let and const from client-side code * get emit count and emit count period from configuration * reduce network cursor updates a lot to prevent instantly getting banned with the current defaults * prevent eraser from deleting cursors * use group inside of svg as drawing area and only delete elements inside it with the eraser * use transform: translate to move cursors around instead of manipulating x and y directly * fix: add socket ids to cursor messages * fix incorrect remote cursor scaling and make local cursor visible again after it has been moved after being hidden due to inactivity * create cursors in a proper fashion and keep them in a separate group * scaling has been fixed in a1a5580 * move duplicated cursor creation code to function * show cursors above content * pass some of ther server configuration through to the client * fix bug introduced in a833ce9 * allocate at most half of the allowed traffic to cursor updates * remove debugging leftover * use feature detection instead of ua sniffing Co-Authored-By: Ophir LOJKINE <ophir.lojkine@auto-grid.com> * fix regression where local cursor color was not updated on color change * Define the cursor as a tool * Remove the cursor tool from the UI * Throttle remote cursor updates, not local ones * Do not increment notification count on cursor move * Use only one pencil icon Use the same image for the pencil icon in the menu and the pencil cursor that appears while drawing * Add a test for the new cursor feature * only stop drawing remote cursor when using some tools and always draw local cursor * increase idle period before hiding cursor * change idle duration back and set whether a cursor should be sent when using a tool in the respective tool Co-authored-by: Robert Beach <rdbeach@gmail.com> Co-authored-by: Ophir LOJKINE <ophir.lojkine@auto-grid.com> Co-authored-by: ophir <pere.jobs@gmail.com>		2020-05-02 06:13:48 +02:00
