piman@ -- Could you please look into this issue, kindly reassign if it has nothing to do with your changes.

Thank You.

This is the same  crbug.com/783054  but we get a proper stack trace now.

Per https://bugs.chromium.org/p/chromium/issues/detail?id=783054#c3:
This is glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_BASE_LEVEL, param), where param is -7.30157126e-07, which is negative, but rounds to 0.

The decoder first converts to int (by rounding), then validates that it is non-negative.
ANGLE validates that it is non-negative before rounding.

According to the spec (2.3.1 Data Conversion For State-Setting Commands), the decoder does the right thing, so ANGLE should first convert (round) then validate:
"Validation of values performed by state-setting commands is performed after conversion, unless specified otherwise for a specific command."

Validate texture parameters for >0 after rounding.

From the spec (2.3.1 Data Conversion For State-Setting Commands):
"Validation of values performed by state-setting commands is performed
after conversion, unless specified otherwise for a specific command."
