/**

 * Patch luma.gl 9's WEBGLRenderPipeline to tolerate mixed-sampler-type

 * validation errors in _getLinkStatus().

 *

 * WebGL2's validateProgram checks that sampler uniforms of different types

 * (sampler2D, usampler2D, isampler2D) are not assigned to the same texture

 * unit. Before any draw call the default texture unit for all samplers is 0,

 * so programs that mix sampler types (e.g. raster band data as usampler2D +

 * colormap as sampler2D) always fail validation even though the program linked

 * successfully and will work correctly once texture units are assigned at draw

 * time.

 *

 * luma.gl calls validateProgram inside _getLinkStatus() immediately after

 * linkProgram, before any texture units can be assigned. This patch keeps the

 * full validateProgram call but ignores only the known false-positive about

 * mixed sampler types. All other validation errors are still reported.
