GetTexImageOES is used even if not using OpenGL ES to work around a small issue that

happens if using custom textures with texture dumping at the same.

Let's say there's 2 textures that are both 32x32 and one of them gets replaced with a
|

|
higher quality 256x256 texture. If the 256x256 texture is displayed first and the
|
||

32x32 texture gets uploaded to the same underlying OpenGL texture, the 32x32 texture
|
||
|
will appear in the corner of the 256x256 texture. If texture dumping is enabled and
|
||
|
the 32x32 is undumped, Citra will attempt to dump it. Since the underlying OpenGL
|
||
|
texture is still 256x256, Citra crashes because it thinks the texture is only 32x32.
|

GetTexImageOES conveniently only dumps the specified region, and works on both

desktop and ES.
