bitmap for testing

When a partially visible sprites are drawn to the screen, fps drops really
badly.

code tested:
https://gist.github.com/vfjpl/bd442e34036547e4ccb05200762fa274

fully visible = 73.8 fps
fully invisible = 394 fps
partially visible = 5.75 fps

The same situation is happening on Allegro library. I don't know enough OpenGL
to test it directly.

I can provide more test results. Just ask me to do it.

Extended renderer info (GLX_MESA_query_renderer):
    Vendor: X.Org R300 Project (0x1002)
    Device: ATI RC410 (0x5a62)
    Version: 17.3.7
    Accelerated: yes
    Video memory: 128MB
    Unified memory: no
    Preferred profile: compat (0x2)
    Max core profile version: 0.0
    Max compat profile version: 2.1
    Max GLES1 profile version: 1.1
    Max GLES[23] profile version: 2.0

And small question. Why Max core profile shows 0.0? Should I open another
bug-report?
