Revision [12087]

Additions:

The function employs window clipping by default. Text lines that are
detected as lying completely outside the 'win'dow will not be drawn, but
clipped away. This allows to draw multi-page text (multiple screen
heights) without too much loss of drawing speed. If you find the clipping
to interfere with text layout of exotic texts/fonts at exotic sizes and
formatting, you can define the global variable...
global ptb_drawformattedtext_disableClipping;
... and set it like this ...
ptb_drawformattedtext_disableClipping = 1;
... to disable the clipping.
Clipping also gets disabled if you request the optional 3rd return
parameter 'textbounds' to ensure correct computation of a bounding box
that covers the complete text. You can enforce clipping by setting
ptb_drawformattedtext_disableClipping = -1; however, computed bounding
boxes will then only describe the currently visible (non-clipped) text.

Additions:

[nx, ny, textbounds] = DrawFormattedText(win, tstring [, sx][, sy][, color][, wrapat][, flipHorizontal][, flipVertical][, vSpacing][, righttoleft])
WrapString function (See 'help WrapString'). 'wrapat' mode may not work
reliably with non-ASCII text strings, e.g., UTF-8 encoded uint8 strings
on all systems.
The optional argument 'righttoleft' if set to 1, will ask to draw the
text string in right-to-left reading direction, e.g., for scripts which
read right to left

Deletions:

[nx, ny, textbounds] = DrawFormattedText(win, tstring [, sx][, sy][, color][, wrapat][, flipHorizontal][, flipVertical][, vSpacing])
WrapString function (See 'help WrapString').
