wineps.drv: Add support for TrueType composite glyph transforms.

[Dmitry Timoshkov]

This patch fixes printing of Cyrillic capital letter Ya (0x042f) and other
cyrillic letters from arial.ttf font with dlls/wineps.drv/generic.ppd and
similar PPD files which specify '*TTRasterizer: None'.

For example, Cyrillic capital letter Ya (0x042f) is just a reference to
Latin capital letter R with a mirroring in x-axis transform applied.
