Dear Maintainer,

When I run dizzy from an xterm, it crashes with these lines:
--- begin of output ---

GPU features: [x] GLSL     [x] FBOs
Shader compilation failed: 0(2) : warning C1503: undefined variable
"UNKNOWN_padsv_store_OP"
0(3) : warning C1503: undefined variable "var6"
0(1) : error C1008: undefined variable "UNKNOWN_padsv_store_OP"
0(3) : error C1008: undefined variable "var6"

Shader source:
void main() { float var1 = gl_TexCoord[0].x - 0.5; float var2 =
gl_TexCoord[0].y - 0.5;
UNKNOWN_padsv_store_OP;
float retval = ((sin((3.14159265358979 / (0.0001 + (2. * var6)))) / 2.) + 0.5);
gl_FragColor = vec4(vec3(retval), 1.0); }

Died at /usr/share/perl5/Dizzy/TextureGenerator.pm line 135.
--- end of output --- Either my graphic card is not powerful enough, either my driver is not up to date, or maybe something is missing in dizzy (var6 variable seems not to have been defined). Yours, n.

The interesting part of the issue looks to be the beginning:

For a moment, I thought that Damyan's ignore-unknown-ops.patch
would be somewhat related and tried something looking like:
