[Mono-winforms-list] Private ImageList methods removed in r69012

I got some weird results (I used Visual Studio 2005):
Private Reset... methods are ignored but private ShouldSerialize... methods
Previously I didn't realize this behavior.
Note ShouldSerialize... does not affect the property browser but affects the
designer generated code and it is definitely affected by private
Previosuly I added this comment:
// MS.NET 2.0 initializes TransparentColor to Color.Transparent in
// constructors but ResetTransparentColor and
// default to Color.LightGray that is treated as a bug.
But now that .NET Framework 2.0 is already released and this wasn't fixed we
should follow MS.NET behavior if we reintroduce the remove methods.
The private Reset... methods are ignored by Visual Studio and I'm not sure
whether we should implement them:
- Implementing them is good because it provides consistency with
ShouldSerialize... that follows the specification
(http://msdn2.microsoft.com/en-us/library/53b8022e.aspx) and other designers
can use it and future Visual Studio versions may use it.
- Implementing them is useless because they are not used.
I think we should implement ShouldSerialize... methods because they are

I had a minute so I did what you asked in vs2003.
For the imagelist properties:
1. Color Depth:
Initial: Property name is not bold, property value is not bold,
Changed: Property name is not bold, property value becomes bold,
reset is enabled.
2. ImageSize and Transparent Color (both act the same)
Initial: Property name is not bold, property value is bold, reset
Changed: Property name is not bold, property value is bold, reset
Hope this helps.

so I just brought up visual c# express (which is admittedly 2.0) and
none of the image list properties affected (ColorDepth, ImageSize,
TransparentColor) acted as if they had a Reset or ShouldSerialize
from that article, an easy way to determine this is:
1. select the ImageList in the design surface.
2. Look at its properties. If a property is in bold, it doesn't have a
ShouldSerialize method (and also doesn't have a DefaultValue attribute,
but that's irrelevant here).
3. change the value of the property, then right click on it. If the
"Reset" item in the menu is disabled ,the property lacks a Reset method
(and also lacks a DefaultValue attribute, but again that's irrelevant).
in all three cases, the property was bold at the start, and the reset
menu item was never enabled. Would someone mind doing the above 3 steps
on those three properties inside vs2003?
are these methods used in another context outside of designers? If not,
I'd say removing them was the right change. If they're needed in 1.1
I'll add them back in ifdefed for 1.1 and make them internal instead of
private to keep the warnings down.
