[Bug 24800] New: wine try to use float texture even if driver don't support them

Summary: wine try to use float texture even if driver don't
                    support them
           Product: Wine
           Version: 1.2.1
          Platform: x86
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2

wine output with mesa git master r300 gallium driver

The game Panzers II shows lot of wine warnings and mesa errors like:
Mesa: User error: GL_INVALID_VALUE in glTexImage2D(internalFormat=0x822e)
err:d3d:check_fbo_compat >>>>>>>>>>>>>>>>> GL_INVALID_VALUE (0x501) from
Framebuffer format check @ utils.c / 968
fixme:d3d:check_fbo_compat Format WINED3DFMT_R32_FLOAT with rendertarget flag
is not supported as FBO color attachment, and no fallback specified.

Full output is attached.

According to a mesa developer the problem is that current mesa git master
implements ARB_texture_rg and wine thinks it also support R16G16_FLOAT
textures:
https://bugs.freedesktop.org/show_bug.cgi?id=30823

Indeed when disabling such mesa extension with the env variable:
MESA_EXTENSION_OVERRIDE=-GL_ARB_texture_rg

the warnings no longer appear (output also attached).

Other than the warning I see no obvious visual differences. I am using wine
1.2.1 found on Ubuntu 10.10 with a Radeon X1600 (RV530) card using the gallium
r300 driver.

What does the output of glxinfo look like? After having a more closer look at
the spec it seems to say that while texture_rg adds single and dual color
formats, the float versions are only around when ARB_texture_float is also
around. Right now we indeed only check for texture_rg and assume in case it is
around, the float formats must also be around.

This is a known issue. The format table can currently only check for a single
extension.

Can this backported to 1.2.x?

Probably, it's not very invasive.

Backport for wine-1.2.2, works for me.
