Main viewing window

[skywolf829]

The frontend should have a primary viewing window to view the rendered GS model. Interacting in this window (mouse, WSAD, etc) should move a viewing camera in the backend, which is used to render the model.

Requirements

• A window in the application that will display rendered images. AppCommunicator should listen for a messages with the rendered image to display and update the window with the new image.
• Click and dragging (with/without control/shift modifiers), or WSAD+mouse movement, should transmit data to the backend so it can update the camera model.
• The viewing window's resolution should be kept and sent to the backend camera model each time it changes (on window resize)

Created a Render Window window that is created by default with size 400x400. Dearpygui uses a texture system for drawing images to a window, but resizing the texture is not supported. Instead, I allocate a large texture (2000x2000) which is the maximal size for any rendered images. When new render images arrive from the backend, i overwrite just the top left corner of the texture.

On window resize, adjusts how much of the texture is displayed to screen with a uv_max = (x,y) maximum coordinate value, scaling based on width/2000, height/2000 (since 2000 is the size i set the texture to). When the mouse is released from resizing, computation takes place for updating texture.

Larger texture could be supported, but may not be necessary.

Still need to check refresh rate to make sure it can handle 200+ fps

Frontend can handle very high FPS, no worries about receiving high framerate incoming. Likely will be networking bottleneck in the end.
