Add "TextBox" to eeschema
Add "TextBox" graphical item to eeschema before feature freeze
TextBox - rectangle with colorful background and frame border, containing aligned text. Useful for users to add comments, changelogs and make documentation nicer. I suspect, that adding new graphical items will be unavailable when v6 schematics file format will settle.
Requirements:
Background (fill): color and transparency;
Border: color, transparency, line width, line type. Borderless, in case transparency is 100%, or color == background color;
Text: multiline, horizontal justification, font name (arial/consolas), font size, font style (bold/italic). In case system fonts cannot be used, please make an option to choose between default font or monospaced font, like "consolas". Using monospaced font allows user to create table like textboxes, for example - describe pinout of the connector nicely.
Alignment: Vertical text alignment (upper / center / lower).
Margin: number of pixels (or mils) to wraptext / keep away from border.
Option to use monospaced font should be beneficial to pcbnew also (for creating nicely aligned tables on silkscreen)
