[WIN32K]
- Rewrite coordinate transformation code to use XFORMOBJ apis instead of using floating
point in kernel mode. As a small present fix 14 gdi32_winetests (5 mapping, 9 bitmap)
I disabled some RtoL code, since it didn't work anyway and caused more bugs than it
fixed.

+/* Coordinate translation overview
+ * -------------------------------
+ *
+ * Windows uses 3 different coordinate systems, referred to as world space,
+ * page space and device space.
+ *
+ * Device space:
+ * This is the coordinate system of the physical device that displays the
+ * graphics. One unit matches one pixel of the surface. The coordinate system
+ * is always orthogonal.
+ *
+ * Page space:
+ * This is the coordinate system on the screen or on the paper layout for
+ * printer devices. The coordinate system is also orthogonal but one unit
+ * does not neccesarily match one pixel. Instead there are different mapping
+ * modes that can be set using SetMapMode() that specify how page space units
+ * are transformed into device space units. These mapping modes are:
+ * - MM_TEXT: One unit matches one unit in device space (one pixel)
+ * - MM_TWIPS One unit matches 1/20 point (1/1440 inch)
+ * - MM_LOMETRIC: One unit matches 0.1 millimeter
+ * - MM_HIMETRIC: One unit matches 0.01 millimeter
+ * - MM_LOENGLISH: One unit matches 0.01 inch
+ * - MM_HIENGLISH: One unit matches 0.001 inch
+ * - MM_ISOTROPIC:
+ * - MM_ANISOTROPIC:
+ * If the mapping mode is either MM_ISOTROPIC or MM_ANISOTROPIC, the actual
+ * transormation is calculated from the window and viewport extension.
+ * The window extension can be set using SetWindowExtEx() and describes the
+ * extents of an arbitrary window (not to confuse with the gui element!) in
+ * page space coordinates.
+ * The viewport extension can be set using SetViewportExtEx() and describes
+ * the extent of the same window in device space coordinates. If the mapping
+ * mode is MM_ISOTROPIC one of the viewport extensions can be adjusted by GDI
+ * to make sure the mapping stays isotropic, that is it has the same x/y ratio
+ * as the window extension.
+ *
+ * World space:
+ * World space is the coordinate system that is used for all GDI drawing
+ * operations. The metrics of this coordinate system depend on the DCs
+ * graphics mode, which can be set using SetGraphicsMode().
+ * If the graphics mode is GM_COMPATIBLE, world space is identical to page
+ * space and no additional transformation is applied.
+ * If the graphics mode is GM_ADVANCED, an arbitrary coordinate transformation
+ * can be set using SetWorldTransform(), which is applied to transform world
+ * space coordinates into page space coordinates.
+ *
+ * User mode data
+ * All coordinate translation data is stored in the dc attribute, so the values
+ * might be invalid. This has to be taken into account. Integer values might be
+ * zero, so when a division is made, the value has to be read first and then
+ * checked! For floating point values (FLOATOBJ as well) these restrictions do
+ * not apply, since we cannot get dividy-by-zero exceptions.
+ * Though the result might be a completely random and invalid value, if it was
+ * messed with in an illegal way in user mode. This is not a problem, since the
+ * result of coordinate transformations are never expected to be "valid"
values.
+ * In the worst case, the drawing operation draws rubbish into the DC.
