tinywl: fix geo_box bug in cursor resizing
While trying out the tinywl code, I found that the resize mode was behaving weirdly ... so I looked into code. Turns out the `begin_interactive` method stores the cursor position plus the geo_box position; however, `process_cursor_resize` wasn't taking this into account, causing windows to jump down in size unexpectedly when resized and lose alignment with the cursor. To fix this, I simply added a member to the `tinywl_server` struct that stores the geo_box when the mouse enters grab mode, and I referenced that data in the resize method. I considered polling for this data every time instead of storing it in the server struct, but 1) since changes in this value are not relevant and 2) it could potentially decrease performance (I don't know enough about wlroots to know how much) I decided to just store it. I can change this if desired.
