* fix window size on creation * rename `logical_width` & `logical_height` back to `width` & `height` * update `Camera` trait to take width/height as `f32` * update `WindowResized` to report 'f32' sizes instead if `u32` * update `WindowCommand::SetResolution` to pass physical resolution instead of logical * put `set_resolution` back, now taking `f32` instead of `u32` * remove several unneeded `as f32`s now that `width` & `height` returns `f32`
* add back `logical_width` & `logical_height` so that code that wants full precision still has access, updated several places in engine that wanted `f32` to use these.

While resizing a window on a high DPI display, some window sizes cause an off by one error when recalculating the physical size of the window. This causes the swap chain to fail to resize until the window resized again to a "good" resolution. The issue is caused by the logical size being stored as an integer which looses precision when calculated from the physical size.
This patch attempts to solve the issue by storing the physical resolution of the window instead of the logical resolution. As part of the effort,
width&heightbecomelogical_width&logical_height,scaled_width&scaled_heightbecomephysical_width&physical_height. This requires touching a number of things and will probably break downstream users. It also changes the type of the components of the logical size tof32so it can better represent sizes that are a fraction of a pixel.
