gdi32: Partially implement HALFTONE stretch mode.
...
COLORONCOLOR(STRETCH_DELETESCANS) was used in place of HALFTONE. COLORONCOLOR mode may delete rows
of pixels without trying to preserve information so it will cause Wine to render poorly when the
destination rectangle is small.
According to tests, HALFTONE mode uses box filter when doing integer downscaling and nearest
neighbor interpolation when doing upscaling in both horizontally and vertically. In other cases,
HALFTONE mode uses a lanczos3 like algorithm to interpolate pixels. There are also other heuristics
involved. For example, shrinking a 2x2 image to 1x1 may not use box filter depending on image data.
Since this algorithm is undocumented, it's difficult to reverse engineer the original algorithm and
produce identical results. Instead, this patch uses a naive implementation of bilinear interpolation
to implement HALFTONE mode and it produces good quality images.
For 8-bit and lower color depth images, nulldrv_StretchBlt should resize the images first and then
converts color depth.

gdi32: Move the loop through each clipped rectangle to the primitive blend funcs.

This is to prepare so we don't recalculate the lookup cache map for color
tables on every clipped rect (which is expensive).

gdi32: Add a mask_rect primitive for use when the src is 1bpp.
...
This essentially combines the format conversion with a copy_rect.
It cannot be used when stretching, since stretching of 1bpp is
slightly special. Similarly, it cannot be used if the dst is also
1bpp (hence there is no mask_rect_1) or if the rop involves the brush.
