[PATCH 3/5] d2d1: Use newer blend options in d2d_device_context_SetTarget() for bitmaps of D2D1_ALPHA_MODE_IGNORE.

[Zhiyi Zhang]

When bitmap alpha mode is D2D1_ALPHA_MODE_IGNORE, D3D11_BLEND_ZERO is used for SrcBlendAlpha and
D3D11_BLEND_ONE for DestBlendAlpha on Win7. However, tests show that D3D11_BLEND_ONE is used for
SrcBlendAlpha and D3D11_BLEND_INV_SRC_ALPHA for DestBlendAlpha on Win8+. The patch changes
d2d_device_context_SetTarget() to use the Win8+ behaviour.

Fix PowerPoint 2016 slideshow artifacts.
