flare.ktx broken #44
Description
Hi,
the mirrorclampedge example results in black screen. I tracked down the reason down to the flare.ktx being most likely broken.
The problem being:
---------------
GL_INVALID_ENUM in glTexStorage2D(internalformat = GL_RGB)
Message ID: 5
Source: API
Type: Error
Severity: high
---------------
GL_INVALID_OPERATION in glTexSubImage2D(invalid texture level 0)
Message ID: 5
Source: API
Type: Error
Severity: high
---------------
GL_INVALID_OPERATION in glGenerateMipmap(zero size base image)
Message ID: 5
Source: API
Type: Error
Severity: high
ktxinfo utility says the following:
> ktxinfo flare.ktx
Header
�KTX 11�

������
endianness: 0x4030201

The KTX 1 file pHeader is invalid:
it has invalid data such as bad glTypSize, improper dimensions,
improper number of faces or too many levels.
Do you have working version of flare.ktx?

the ktxinfo actually will report every ktx file under media/textures/ as:
BTW, my mirrorclampedge show black too.
