Zoompeace

This patch disables control-mouse-wheel-to-zoom-text in the editor for Mac by default, and enables it by default for Windows/Linux. It also adds an option in preferences to turn it on and off. 


there have been many bug reports, and mailing list discussions, mostly from Mac users, about mouse-scroll-wheel zooming of text being a problem in the editor. 

the control+mouse-wheel to zoom text is almost a de-facto standard in the linux/windows world. it is used by every major web browser, microsoft word, kate, libreoffice, visual studio, and numerous other text editing programs. 

i can only assume the mouse-wheel zoom is used on linux/windows(tm) because the wide variety of monitor sizes and resolutions you deal with in the PC world, and the fact that almost all mice for the past 10+ years in the PC world have had scrollwheels... other than laptops, which have adopted the two-finger-drag as scrollwheel equivalent.

i can only assume things are different in mac because of more standardized screen sizes, as well as the fact that almost all mac mice do not have scrollwheels.

obviously a certain amount of people hate it. a small sampling of the web.

google searches:

"firefox mouse-wheel zoom"
"enable mouse-wheel zoom"

Here are people hating on Visual Studio for implementing it

This patch will try to adopt the 'typical' behavior expected for most users (disabled for Mac, enabled for Linux/Win), and allow those who hate it to disable it as their preference.
