Subject: [PATCH] `WebRenderer.snapshotFramebuffer` and by extension, the
 snapshot methods in Dynamic Textures and Render Textures, has been updated to
 ensure that the width and height never exceed the framebuffer dimensions, or
 it'll cause a runtime error. The method `snapshotArea` has had this
 limitation removed as a result, allowing you to snapshot areas that are
 larger than the Canvas. Fix #5707
