Potential bug in ScintillaWin::WndPaint

[Farshid Lashkari]

I have a case where I need the Scintilla window to draw to a specific HDC.
I manually send the WM_PAINT message to the Scintilla window with a
PAINTSTRUCT in the wParam field. I'm finding that this does not always work
correctly. I believe the problem is that the ScintillaWin::WndPaint method
will trigger a full repaint if the paint was abandoned. However, it does
not use the specified HDC in this case. I modified the following code at
the end of ScintillaWin::WndPaint:

if (paintState == paintAbandoned) {
// Painting area was insufficient to cover new styling or brace
highlight positions
FullPaint();
}

to:

if (paintState == paintAbandoned) {
// Painting area was insufficient to cover new styling or brace
highlight positions
if (IsOcxCtrl) {
FullPaintDC(pps->hdc);
} else {
FullPaint();
}
}

This appears to have solved the painting issues I was having.
