ImDrawList missing ImVec2 arguments

[immetoo2]

To learn the ImDrawList interface have recoded some of the FX drawing contests code to imgui-java from;
ocornut/imgui#3606

		ImGuiIO io = ImGui.getIO();
		ImVec2 size = new ImVec2(320f, 180f);
		ImGui.begin("FX", ImGuiWindowFlags.AlwaysAutoResize);
		ImGui.invisibleButton("canvas", size.x, size.y);
		ImVec2 p0 = ImGui.getItemRectMin();
		ImVec2 p1 = ImGui.getItemRectMax();
		ImDrawList drawList = ImGui.getWindowDrawList();
		drawList.pushClipRect(p0.x, p0.y, p1.x, p1.y);
		
		ImVec4 mouseData = new ImVec4();
		mouseData.x = (io.getMousePosX() - p0.x) / size.x;
		mouseData.y = (io.getMousePosY() - p0.y) / size.y;
		mouseData.z = io.getMouseDoubleClickMaxDist(); // ??
		mouseData.w = io.getMouseDragThreshold();      // ??
		
		double imTime = ImGui.getTime();
		
		FX(drawList, p0, p1, size, mouseData, (float)imTime);
		
		drawList.popClipRect();
		ImGui.end();

And two FX effects;

	void FX(ImDrawList d, ImVec2 a, ImVec2 b, ImVec2 sz, ImVec4 mouse, float t)
	{
		float sx = 1.f / 16.f;
		float sy = 1.f / 9.f;
		for (float ty = 0.0f; ty < 1.0f; ty += sy) {
			for (float tx = 0.0f; tx < 1.0f; tx += sx) {
				ImVec2 c = new ImVec2((tx + 0.5f * sx), (ty + 0.5f * sy));
				float k = 0.45f;
				d.addRectFilled(
					a.x + (c.x - k * sx) * sz.x, a.y + (c.y - k * sy) * sz.y,
					a.x + (c.x + k * sx) * sz.x, a.y + (c.y + k * sy) * sz.y,
					ImColor.intToColor((int)(ty * 200), (int)(tx * 255), 100, 255)
				);
			}
		}
	}

	void FX(ImDrawList d, ImVec2 a, ImVec2 b, ImVec2 sz, ImVec4 mouse, float t)
	{
		for (int n = 0; n < (1.0f + Math.sin(t * 5.7f)) * 40.0f; n++) {
			d.addCircle(a.x + sz.x * 0.5f, a.y + sz.y * 0.5f, sz.y * (0.01f + n * 0.03f), 
				ImColor.intToColor(255, 140 - n * 4, n * 3, 255)
			);
		}
	}

It would be very nice to also have the ImVec2 arguments in the ImDrawList methods.
