Fix particle sizes, and add tools for comparing renderers

Particles: Direct3D 9's size limit evidently isn't the documented 64 pixels; unclamped (up to 2048) they match the client's renderer. A compare view shows the left half's scene over the right half, both renderers side by side; %TEMP%\t5de-renderer-view.txt switches views and %TEMP%\t5de-renderer-shaders\fixed_function.hlsl replaces the shaders while the client runs. The renderer process runs from a copy, so the program can be replaced meanwhile. The adapter recognizes only the textures and buffers it made (others reach the client renderer unchanged) and logs the others and render targets.
