Subject: [PATCH] Fix crash in swrast when setting a texture for a pixmap.

When  getImage() is called in swrastSetTexBuffer2() there will be
a crash somewhere down the line since texImage->Data isn't initialized
which holds a pointer to the destination.
To initialize texImage->Data we call ctx->Driver.TexImage2D().
