This fixes a bug where when the size of the map editor changes, the grid shader's internally stored value for the size of the map editor's viewport doesn't get updated until one frame later if the shader is using push constants. This caused the thicknesses of the grid lines to be inaccurate for a frame after resizing.

* fix: fix 1 frame delay when grid shader viewport size changes This fixes a bug where when the size of the map editor changes, the grid shader's internally stored value for the size of the map editor's viewport doesn't get updated until one frame later if the shader is using push constants. This caused the thicknesses of the grid lines to be inaccurate for a frame after resizing. * feat: add "Save map preview" button for saving map as image * style: replace `ScreenshotState` with an async block * perf: don't use padding in the texture when screenshotting * feat: handle screenshotting for maps larger than max texture size * fix: fix `width_padded` alignment value * style: remove unnecessary rounding from `max_texture_width`

Description
This pull request adds a "Save map preview" button to the map editor that saves the current state of the map, with all currently visible layers, as a PNG file.
The implementation is in the
save_as_imagefunction in crates/components/src/map_view.rs.Testing
On an arbitrary map, the button should be able to correctly render all visible map layers and events, with layer darkening if it's enabled. Also it should be able to render the grid and collision layers if they're enabled. It should also be able to render maps that are larger than the maximum texture dimensions allowed by wgpu (it does this by breaking the map into large tiles and rendering them individually before combining them together).
