/***********************************************************************
* CreateBrushIndirect (GDI32.@)
*
* Create a logical brush with a given style, color or pattern.
*
* PARAMS
* brush [I] Pointer to a LOGBRUSH structure describing the desired brush.
*
* RETURNS
* A handle to the created brush, or a NULL handle if the brush cannot be
* created.
*
* NOTES
* - The brush returned should be freed by the caller using DeleteObject()
* when it is no longer required.
* - Windows 95 and earlier cannot create brushes from bitmaps or DIBs larger
* than 8x8 pixels. If a larger bitmap is given, only a portion of the bitmap
* is used.
