Applied patch [ 588140 ] User Scaling of Rotated Text on wxGTK

The effect of wxDC::SetUserScale() on
wxDC::DrawRotatedText() is to scale the text **twice**.
The code is in src/gtk/dcclient.cpp

The first scaling operation occurs when choosing the
GTK font size (as happens for wxDC::DrawText()). The
rotated text is scaled a second time when blitting the
rotated text bitmap to the DC, in the functions
XLOG2DEV(x + dstX) and YLOG2DEV(y + dstY).

The supplied patch moves the rotated bitmap co-ords
(dstX, dstY) outside of the LOG2DEV functions.
