Bug 467431

Description of problem:
It is no longer possible to set colors correctly in Inkscape.
As a result, most colors are unavailable (including the basic ones as white, yellow, etc.) and Inkscape is totally unusable.

This is because the maximum value for any color slider is 245, which is enforced by to GTK+ >= 2.13.

This is well described in:

GTK folks claim this is correct behaviour:
Copied from gnome bugzilla:
------- Comment #1 from Matthias Clasen 2008-09-04 00:47 UTC -------
 GTK+ is simply enforcing documented behaviour now. The fix is to set page_size
 to 0 when using adjustments for simple scalar values, such as in a slider.

>From the release notes: 
* GtkAdjustment now enforces that values are restricted to the
   range [lower, upper - page_size]. This has always been the documented
   behaviour, and the recommended practice is to set page_size to 0
   when using adjustments for simple scalar values, like in a slider
   or spin button.

Version-Release number of selected component (if applicable):
inkscape-0.46-5.fc10.x86_64

How reproducible: Always


Steps to Reproduce:
1. Open Inkscape
2. Create an object
3. Try to set its color to white (or any color with a value of >245 in any of its components.
  
Actual results:
Maximum value of all components is 245.
Standard colors are unavailable.

Expected results:
Being able to set values from 0 to 255 included.
