{
Miranda Service-functions defined by MathModule
call with the
int ( CallService)(const AnsiChar servicename,WPARAM,LPARAM)
that you get from miranda when Miranda calls the
Load(PLUGINLINK link)
of your PlugIn-dll
the CallService function then is:
link->CallServiceSync(Servicename,wparam,lparam)
}

{ Strange things happen if you use this function twice on the same CHARRANGE: }
{ if Math-startDelimiter == Math-endDelimiter, there is the following problem: }
{ it might be that someone forgot an endDelimiter, this results in a lonesome startdelimiter. }
{ if you try to MATH_REPLACE_FORMULAE the second time, startDelimiters and endDelimiters are mixed up. }
{ The same problem occours if we have empty formulae, because two succeding delimiters are }
{ replaced with a single delimiter. }

// MathModule can insert Formula-elements from
// the Math-Toolbox.
// you can make the BKGCOLOR Transparent (default) by using this color:
TRANSPARENT_Color = $FFFFFFFF-1; // this is default
const

{returns Bitmap that represents the formula given in lparam (string-pointer) }
{this formula has NO Delimiters. }

{ todo: umbenennen in MTH_Set_ResizeWindowHandle, zusaetzlich MTH_Set_ToolboxEditHandle erstellen, dann keine SRMM-Abhaengigkeit mehr. }
{ damit ResizeWindows selbst entscheiden koennen, was sie tun, kann man auch ein miranda-event "MTH_preview_resized" einrichten. }

{ returns the height of the whole preview-window (including system-menu-bar) }
