`Renderer.blit()` doesn't check if the texture is created by another renderer.

[yunline]

import pygame
from pygame._sdl2.video import Window, Renderer, Texture

pygame.init()

img = pygame.Surface((128,128))
img.fill("red")

win1 = Window("win1")
win2 = Window("win2")

ren1 = Renderer(win1)
ren2 = Renderer(win2)

tex2 = Texture.from_surface(ren2, img)

ren1.blit(tex2, (0,0))

ren1.present()
ren2.present()

while 1:
    pygame.event.get()

In this example, user trys to blit tex2 (created by ren2) to ren1. Then the tex2 is draw to the ren2, without any warning or error raised.

What's more? If an object that has a draw method is passed to Renderer.blit, then the draw method will be called without any checking, even though the draw function never draws on the Renderer.

So I suggest:

• Renderer.blit() should only accept Texture, Image (and Surface?) and their subclasses.
• Renderer.blit() should check if the Texture is created by itself.
