Fermi2D: limit blit area to only available area

Browse source 
Normaly OpenGL does not care if the areas exceed the texture regions but
other backends such as Vulkan do care about the limits of this areas.
This PR crops the areas of the blit in order that they don't surpass the
limits of the textures. This should help Vulkan and faulty OpenGL
drivers
