replaced ColorEdit4() third parameter 'bool show_alpha=true' to 'ImGuiColorEditFlags flags=0x01' where ImGuiColorEditFlags_Alpha=0x01 for dodgy compatibility replaced ColorEdit4() third parameter 'bool show_alpha=true' to 'ImGuiColorEditFlags flags=0x01' where ImGuiColorEditFlags_Alpha=0x01 for dodgy compatibility

Note that higher-level ImGui::PushClipRect() is preferable because it will clip at logic/widget level, whereas ImDrawList::PushClipRect() only affect your renderer.
- 2016/04/03 (1.48) - removed style.WindowFillAlphaDefault setting which was redundant. Bake default BG alpha inside style.Colors[ImGuiCol_WindowBg] and all other Bg color values.
