* We don't want to enable this on all cards, as it adds an extra instruction per texcoord used. This
* makes the shader slower and eats instruction slots which should be available to the d3d app.
*
* ATI Radeon HD 2xxx cards on MacOS have the issue. Instead of checking for the buggy cards blacklist
* all radeon cards on Macs but whitelist the good ones, that way we're prepared for the future. If
* this workaround is activated on cards that do not need it it won't break things, just affect
* performance negatively
