Ability to modify Ui.Text and Ui.Bitmap

It is nice to be able to use the helper classes Ui.Text and Ui.Bitmap. Unfortunately, while you can modify the position and size of them both, you can't modify any of the other attributes. For instance, the following methods would be nice to have...

module WatchUI {

class Text {

function setColor(color) {
mColor = color;
}

function setFont(font) {
mFont = font;
}

function setText(text) {
mText = text;
}

function setJustification(justify) {
mJustification = justify;
}
}

class Bitmap {

function setBitmap(rezid) {
mRezId = rezid;
}
}

}
