Patch: Solve the problem of "floated value" in map elements

[spaww]

Hi all,

Aleatory apear a BUG (related with some numbers in support.zabbix.com, like related in: ZBX-7174) and the browser change the user input adding a decimal value like:

User set a width: 202 height: 201 (or some other value)
Click on "Apply"
Interface change to
Width: 202.55555534362793
Height: 201.55555534362793

I solve the problem changing file js/class.cmap.js

Lines 1058 and 1059 (Zabbix 2.2.3rc1)
OLD:
this.data.width = newWidth;
this.data.height = newHeight;

NEW:
this.data.width = Math.floor(newWidth);
this.data.height = Math.floor(newHeight);

I test on Chrome and Firefox (Internet explorer no... someone can try ? ) and solve the problem for me !
