[PATCH v2 0/2] MR10162: d2d1: Clamp opacity value for d2d_device_context_draw_bitmap().

[Zhiyi Zhang (＠zhiyi)]

Some applications call DrawBitmap() with the opacity value set to 255.0f and end up showing white in
the end result. Tests show that the opacity value should be clamped to legitimate values. Command
lists store the original opacity value according to tests.
