[PATCH v6 0/6] gdi32/win32u: EMF fixes to support Hancom Office 2020

[Jinoh Kang]

The following commits modify the behaviours of the following GDI functions:

- StretchDIBits
- SetDIBitsToDevice

To match more closely to that of Windows 10, build 2108,
subject to the following constraints:

- The source image is not a JPEG (BI_JPEG) or a PNG (BI_PNG) image.
- The source image is a *bottom-up* device-independent bitmap.

Changelog:

- v1 -> v2: add more tests, do extra work so that EMF outputs match
- v2 -> v3: emf_parse_user_bitmapinfo: zero out *dst (BITMAPINFOHEADER)
  (gdi32: allow passing BITMAPINFO with bmiHeader.biSizeImage == 0 for EMF DC.)
- v3 -> v4: no changes (resend due to borked up patch orders)
- v4 -> v5: change subject (no more RFC); address review comments so far
- v5 -> v6: remove two EMFDRV functions entirely
            clarify code in EMF DC patch
	    uppercase subjects

Jinoh Kang (6):
  win32u: Remove EMFDRV_StretchDIBits and EMFDRV_SetDIBitsToDevice.
  gdi32/tests: Add tests for recording StretchDIBits in EMFs.
  gdi32/tests: Add tests for recording SetDIBitsToDevice in EMFs.
  gdi32: Fix bounding box calculation for EMR_STRETCHDIBITS.
  gdi32: Allow passing BITMAPINFO with bmiHeader.biSizeImage == 0 for
    EMF DC.
  gdi32: Calculate effective number of scan lines and truncate bitmap
    bits for EMR_SETDIBITSTODEVICE.
