After the latest update, the freshly updated updater

again looked a bit hollow, missing the background texture.
The reason was clear: Once upon a time, I had to add
Video.OpenGL.UseExtension.GL_NV_texture_rectangle = false to the file
data/config/r3dopengl.cfg (and updates usually overwrite this file again and again). And I know for sure that this is the only extension I need to disable.
But today I had a look at
data/config/gldrivers.xml and decided that this should be the best area to introduce a fix. To be safe, I created new configs and rules, especially for my graphic card: GeForce2 GTS.
GLInfo2 reported my renderer as "GeForce2 GTS/AGP/3DNOW!". So I added the following entries:
<config name="disableNVRECTTextures">
<Video>
<OpenGL>
<UseExtension>
<GL_NV_texture_rectangle>no</GL_NV_texture_rectangle>
</UseExtension>
</OpenGL>
</Video>
</config>
<rule description="GeForce2 GTS: NV_RECT texture extension support apparently sucks">
<conditions fulfill="one">
<regexp string="renderer" pattern="GeForce2.GTS" />
</conditions>
<applicable>
<usecfg>disableNVRECTTextures</usecfg>
</applicable>
</rule>

Found my previous mistake. Regular expressions exist in several varieties. Here, a dot means "any one char", and an asterisk means "zero, one or multiple times of the preceding symbol".
