13309	[Patch] Caching and notifying preferences	michael2402	team	"Currently, there are many MapFrame.repaint() calls whenever properties change.

Part of this is because colors and other values are cached by each component seperately.

I added a new infrastructure that allows you to get a property and easily cache that result.

To get a property use:
{{{
#!java
new IntegerProperty(""my.property"", ""123"").get()
}}}

To cache the result, use:
{{{
#!java
prop = new IntegerProperty(""my.property"", ""123""); // registers 123 as default value
prop.get(); // lazy get and convert to int
prop.get(); // get cached integer object
}}}

I added a new preference listener that listens to changes of one specific key to make this efficient."	enhancement	new	normal	16.08	Core			gsoc-core	Don-vip bastiK stoecker
