Class Description

*-*-*-*-*-*-*-*-*-*-*-*-*Text Attributes class*-*-*-*-*-*-*-*-*-*-*-*-*-*-*
*-*                      =====================
*-*  Text attributes are:
*-*    Text Alignment
*-*    Text Color
*-*    Text Font
*-*    Text Size
*-*    Text Angle
*-*
*-*  This class is used (in general by secondary inheritance)
*-*
*-*  by many other classes (graphics, histograms).
*-*    align : Text alignment = 10*HorizontalAlign + VerticalAlign
*-*            For Horizontal alignment the following convention applies:
*-*               1=left adjusted, 2=centered, 3=rigth adjusted
*-*            For Vertical alignment the following convention applies:
*-*               1=bottom adjusted, 2=centered, 3=top adjusted
*-*            For example align = 11 = left adjusted and bottom adjusted
*-*                        align = 32 = right adjusted and vertically centered
*-*    angle : Text angle in degrees
*-*    color : Text Color Index
*-*    font  : Text font code = 10*fontnumber + precision
*-*             Font numbers must be between 1 and 14
*-*             precision = 0 fast hardware fonts (steps in the size)
*-*             precision = 1 scalable and rotatable hardware fonts (see below)
*-*             precision = 2 scalable and rotatable hardware fonts
*-*             precision = 3 scalable and rotatable hardware fonts. Text size
*-*                           is given in pixels.
*-*    size  : Character size expressed in percentage of the current pad height
*-*            The textsize in pixels (say charheight) will be:
*-*             charheight = textsize*canvas_height if current pad is horizontal.
*-*             charheight = textsize*canvas_width  if current pad is vertical.
*-*             charheight = number of pixels if font precision is greater than 2
*-*
*-* Font quality and speed
*-* ======================
*-*  When precision 0 is used, only the original non-scaled system fonts
*-*  are used. The fonts have a minimum (4)  and maximum (37) size in pixels.
*-*  These fonts are fast and are of good quality. Their size varies with
*-*  large steps and they cannot be rotated.
*-*  Precision 1 and 2 fonts have a different behaviour depending if the
*-*  True Type Fonts are used or not. If TTF are used, you always get
*-*  very good quality scalable and rotatable fonts. However TTF are slow.
*-*  Precision 1 and 2 fonts have a different behaviour for Postscript
*-*  in case of TLatex objects. With precision 1, the Postscript text uses
*-*  the old convention (see TPostScript) for some special characters
*-*  to draw sub and superscripts or greek text.
*-*  With precision 2 the "PostScript" special characters are drawn as such.
*-*  To draw sub and superscripts it is highly recommended to use TLatex
*-*  objects instead.
*-*
*-*  How to use True Type Fonts
*-*  ==========================
*-*  You can activate the TTF by adding (or activating) the following line
*-*  in your .rootrc file.
*-*  Unix.*.Root.UseTTFonts:     true
*-*  WinNT  for NT
*-*  You can check that you indeed use the TTF in your Root session.
*-*  When the TTF is active, you get the following message at the start
*-*  of a session:
*-*    "FreeType Engine v1.x used to render TrueType fonts."
*-*  You can also check with the command gEnv->Print().
*-*
*-*  List of the currently supported fonts (screen and PostScript)

 If the font precision is greater than 2, the text size is set to npixels,
 otherwise the text size is computed as a per cent of the pad size.
